I also have been wondering why people want to use Barter primarily when it is so so incredibly slow in finding matches or updating trade information. I suppose most simply do not know about its functionality and we're up against the first mover advantage. I did start a new thread at the Steam community as I noticed that it seems rather quiet there and most people probably do not even bother to look further if there appears little activity there. So what might work best is if a few more new threads are created at the Steam community by other people to show that there is activity. After that, people might have more success in inviting others.

To put the issue of the first mover advantage in perspective in for example the cryptocurrency market, everyone notices that Bitcoin is by the largest, even though there are now vastly superior alternatives. Bitcoin will however not remain the largest. Another example is the internetbubble. Most of the initial massive internet companies are now no longer around or fairly trivial, whilst other giants have come along which took over most of the market such as Google and Amazon. Of course the size of the markets is vastly different, but the same rules generally apply.

I think most people will probably keep using Lestrades if they have tried using it for about a week. The question to me seems how to get people to get to use it for a week. I do not think that giving away something should be necessary at this point. A tutorial might help with getting more users. At a later point it might be interesting to explore how users can be enticed to try it out for a week. Ultimately trading platforms help sellers of games as it improves liquidity. People tend to buy more bundles as they know they can exchange them for other items of interest. So what could potentially work is some kind of cooperation with certain gamebundle sellers. You could for example offer to provide a visible link to their websites in exchange for them offering a link to yours. Websites like Indiegala might like to pretend that their own trading platform is functional, but it really is not. So in that sense all parties stand to win something from such a setup, but the question is whether most gamebundle sellers also notice the strategic advantage from such kind of cooperation.

The alternative you have is to offer a service similar to what G2A has besides the trading platform. In case your prices would be lower than those of G2A, you'd attract an entirely different group of buyers and sellers and you could make money on each transaction. The downside is that you would then not be able to link to gamebundle sellers and vice versa.

As an alternative in case you would be interested in that, you could potentially decide to work together with Steamtrades / Steamgifts and integrate those platforms with what you have. The upside/downside is shared decision making. In case you would be able to integrate platforms, you would have access to a large user base by default. An alternative would be to join forces with Barter. Perhaps you can also join forces with others than the above mentioned who can give you what you need and vice versa.

All in all I think you have a lot of options, but what is most important is that you choose something that you are comfortable with yourself. I think the key questions are first of all whether you would like to run this as a profit or non-profit organisation and secondly how much help you need to accomplish those aims. Many people can have great ideas, but sometimes not all the skills are available to make it into a success. At other times, the cooperation itself can turn a success into a disaster, so best to choose wisely in that regard and set everything forth clearly into contracts in case you decide to work together with others if necessary (also the worst case situations, so that they can be undone relatively easy).

I myself unfortunately cannot offer much help as I am too busy with my own work. I do hope that the above is of some use.

I generally use the following to spot various bundles: Epic Bundle

We can bring in Harvard if that helps:

If you look at the Measles Paradox, you will notice that most measles outbreaks happen in individuals who had been vaccinated:

Measles Paradox

Now of course it could be argued that the influence of the vaccine had weakened over time and it could be argued that the populations were not equally distributed, but that overlooks the low responsiveness of some population groups and the risk those who have vaccinated themselves pose to the rest. The evidence out there does not rule out that model I proposed. Would it not be more appropriate to blame imperfect solutions and work towards something superior? At the end of the day the mainstream scientific world has enough trouble curing a simple cold, without even talking about curing allergies and more advanced diseases. Why be content with that?

As far as placebos are concerned, how would that work with animals who are given homeopathic medicine and measurable results are observed? Would it work because the animal believes in the placebo? The first stage of science would seem to me to be to figure out what works, not why it works. Models have to conform to reality instead of attempting to conform reality to models.

The influence of power on science should never be underestimated. A nice example of this is banking. If privately owned central banks create money and have the monopoly on that creation of money and charge interest on that money (or better said fiat currency), the only thing you know for certain is that on an international level not all parties will be able to repay what they lent. Say a central bank brings $100 into circulation and charges 1% yearly interest (in a protectionist closed off society). How is that society going to come up with $101 by the end of the year when that $100 is the entire money supply? The population has no authority to create that extra $1. It would be called counterfeiting if they created an extra $1 by themselves. Lending more does not circumvent the problem, but it is that reason that that national debts of most countries steadily rise. If science was not compromised in this area, it would have exposed the anomaly. There is either an interest payment or inflation, but both denote an obvious scam.

What people consider as science is not always very scientific. Consider burn marks on your hand. Would you be inclined to put your hand in cold water or hot water when that happens? Have you ever tried purposefully burning both hands and holding one hand in warm water and one hand in cold water? The hand held in warm water will hurt far more initially, but will heal far quicker. Ironic, is it not?

Science is more often the realisation how little we know than the assumption that we know everything. The dominant Aristotelian perspective on science (as opposed to the Platonic perspective) at any rate relies on probabilities to define everything. Here we once again we run into the contradiction that we like to state only certainties, but in Aristotelian science we can only talk about probabilities.

Technically people who take vaccines expose themselves to small quantities of the disease, so they are in essence carriers of it and it is a bit of Russian Roulette whether that infection with disease has enough strength for a full scale breakout and that can spread to others who may or may not be vaccinated. Such information is also listed in the fine print that goes with vaccines, but is never read. So those who let themselves get vaccinated should technically be quarantined from the rest and not the other way around as is often stated. Most of the diseases through the years simply went away though better sanitation and enough food. Homeopathy can actually work very well when considering that the Queen of England uses the best homeopath that country has, Dr. Peter Fisher. It also used to be part of the traditional medicine in the West. Problem is that it is not part of the one problem, one solution concept and might require a somewhat unique treatment for each individual. I have some alternative (non-homeopathic) health procedures myself and whenever I run them there is not a cold that can touch me, even when everyone else around me is ill. Same with other things like removing gallstones (which everyone has) to greatly boost the immune system (and can assist greatly in the curing of all kinds of allergies)....others need to go to the hospital to get some of them surgically removed, but I can remove far more of them in a natural way with some understanding of the body, select salts and oils. People can make life as simple or complicated as they want, but as long as the basic social structure of society remains war the best solutions cannot be expected to be given for free.

The items on the Wishlist currently are never removed after completing a trade. Only a copy of the traded item is removed from Tradables.

Correct, it was $1 together with Civilization III and whilst not likely being offered, Minion Masters in Humble Bundle giftlink format can be resold to a reseller for $2 cash in itself. So all in all it might not have been the greatest deals around in case it was not the better Minion Master version, it was not quite a rip off either in my opinion. In terms of gameplay value, one might have significant emotional attachment to Civilization IV in comparison to all those games offered, so in that sense this can be a great example of why it is important that traders can specify how they value their games or what quantified value they attach to a specific game, so that ignores do not happen due to misunderstandings in the sense of what is a perfectly reasonable offer for one, is completely unacceptable to another.

It still works fine for me. Are both of you logged in? If you are not logged in, I think most of the functionality is not available. In the upper left corner of the provided screenshot the 'Sign in with STEAM' icon is shown.
