How can we stimulate informed discussions, and help BT to grow away from its current emphasis on the crypto underworld, and gain a place in the respectable financial world?
I don't think this will ever happen. When I think about respectable forums, I think about forums with many interested experts. When I think about Bitcointalk, I think about a shitload of spammers who are only here to earn money.
It's not that informed discussions don't exist, it's just a very small fraction, which makes them hard to find. I'll keep doing what I always do: report the bad stuff, merit the good stuff.
