The way I’m currently thinking about it is that reddit was originally designed as a social news website, and you have tack on a bunch of extras if you want your subreddit to do knowledge-accumulation, but phpBB gets you that with much less effort. (Could be as simple as having a culture of “There’s already a thread for that here, you should add your post to it.”)
