If the entire alt section of Bitcointalk was flushed down the toilet tomorrow, it would be step in the right direction for mainstream adoption. The major projects such as NXT, Counterparty, and Bitshares would find a way to collaborate on a new forum or some other free market idea that distance themselves from the complete trash. Anyone feel the need to take a shower after spending 15 minutes around some of these posts?
Do you think the 16 coins that were just delisted by Poloniex were all trash, with devs either being scammers, incompetent, or irrelevant?
I don't dig into smaller projects. This is a reference to the alt section in general that makes Nigerian scammers looks like angels in comparison. If this section disappeared tomorrow, I don't think it would be a huge loss for the type of projects I follow personally. To each their own.
