Im currently thinking about how communication and information exchange can be improved over the internet. You can cut it down to two sides: 'Life' chat (e.g. irc) and 'delayed' chat. With 'delayed' chat I mean all those forum stuff, just like phpBB, vBulletin and StackExchange/Overflow. Now the main question: Is those 'normal' forum software outdated and will dying in future? This is, because the StackExchange system is considered so much better - Best answers are covered at the top, best questions too. Also, the bounty system really makes sense. On a 'normal' forum, an unbelievably awesome answer could be on page 16 of 52 pages. But no one would probably find that one, just for example.
The initial attraction to this question is that I was planning to create a forum (e.g. phpBB or vBulletin) about a specific internet/informatics topic. Thus I was wondering what really to do then, if the stackexchange network does already have a such good service in contrast to 'the others'.
