I feel iffy about it. There's some really interesting posts sometimes, and whenever I have a question about anything, I usually google "my question" + "reddit". Even if it's not always reliable, it does tend to point me in the right direction more times than not.
I really couldn't care less about the community, though. There's a reason why "redditor" is kind of derogatory. Reading the same joke a million times while simultaneously seeing people bitch and whine about reposts is kind of annoying. All the good subs tend to get overrun by the "redditor" crowd sooner or later as well, forcing me to unsubscribe if I don't want my frontpage littered with garbage.
It's good for what it is, but goddamn the people on there are annoying.
