I don't like central silos, but I do love threaded discussion in the style of newsgroups/HN/reddit over message boards. PHPbb is vulnerable to a form of chat flooding where two people start arguing on some piddly issue for several pages and everyone else has to SHOUT LOUDER. The posts of the 2 people get in the way for everyone else and commonly the rest just gives up and the thread dies. In a threaded discussion system, they can face off in their own world.
