This forum is designed to be anti-groupthink. While groupthink has its place, it's the last thing we want to encourage in a revolutionary currency still on the bleeding edge. Speaking of Bitcoin, that brings up a good analogy:
Much like cash is the base form of money, Bitcoin is also a base form of money. Things can be layered on top of it to make it more suitable for a general audience, but you need that base. On the internet, cash can't be transferred directly. You need to use a layered version of cash: credit cards. However, credit cards suck for the merchants. Bitcoin fixes this by making its base form of currency exist on the internet itself, allowing things to be layered on top of it, but not requiring it. If you're following, you probably know where I'm going with this. Without a base form of a place to discuss Bitcoin that isn't censored, you would get stuck using a layer where you might never get heard. Bitcointalk hosts the base of all Bitcoin discussions, allowing information to flow on to the higher, more moderated layers, like StackExchange. In that way, I suppose that you could call us the 4chan of Bitcoin. Try imagining how dull the internet would be if it weren't for 4chan.
