I really believe that this kind amount really puts bitcointalk above any kind of forum out there regarding liquidity.
As for any kind of coin related to the forum, I don't see how that would work. I hardly see it being attached to any kind of value, or at least it would be really hard to channel over attention to it by simply being tied to here. Even having an alt section dedicated to discussion in here doesn't seem to gather a lot of attention for most users, why would a coin created on that intent receive any kind of attention at all?

This forum already had a tremendous impact on the history of crypto as is. We are lucky to experience it in the first hand (some more than others). Let's be happy for what we already achieved, and there's still a lot more that will come in the future.
