Probably because the general internet population is conditioned to a "one place fits all" approach. Reddit, Facebook, Twitter, etc all are places where any content of any kind is welcome. I personally think the Stack Exchange network is effective because it creates communities that specialize rather than a single generalized community. But new arriving users have a preconceived conception that all content is welcome. I think a lot of that could be alleviated by binding together the "Stack Exchange Network" into a more cohesive single site though. Kind of how each subreddit can have its own rules, culture, and community, but it's still very clearly part of Reddit TM. It would be neat if there was a single entry point into the Stack Exchange Network where you could post a question, with a dropdown for selecting which "network" you think is most appropriate. They do appear to slowly be increasing this sort of cross-syndication between network sites, but it definitely has room for improvement.
