Someone please explain to me how your personal reddit, hosted or not, is different from any other forum software such as, say, phpBB2, just as an example. Maybe other forums aren't quite as focused on the voting aspect (though it does exist). Some people see that as an advantage, though. I guess the whole point of having your own social news a.k.a. forum site is so you can dictate what can be posted and what not, to keep the quality and focus on a special subject of your interest.
