You are a honest team and we all know it. But if we should say the things by it's name, the missed opportunity of building a solid community it's your fault. I myself already proposed many times to create some kind of introducing people into gb. It's really simple, it only takes a few coins and some faucet/contests and so on. This coin had one big fail: the PR. With a better PR into the social scene (not reviews into websites that no one really follows nor trusts) things would be greatly different. Reddit, Facebook, Twitter, g+, etc could have been used in a better way. Collaborations with other coins and major investors also. A poker site or a marketplace alone would have never brought people into GB.
At least that's just my 2 cents...
We didn't want to just giveaway a bunch of coins to get people into the community because we felt that would dilute the coin and it's price. We wanted to go the route of getting people to talk about GB, so we worked to get press releases, and try to stir up twitter. Something like a poker site is one thing we focused on heavily, but that developer ran away with the money, and that was after about 3 weeks or so of working with him. The PR maybe could have been better, but if the community had the spread this coin to the people they know and so on, that would make a much bigger impact than anything we could have done. In hindsight things always look clearer though, so I'm not going to say we couldn't have done it better.
