It used to be that blogging carnivals were few and far between, but it seems that there's a regular roundup for everyone, now. The inaugural edition (a.k.a. "First Date") of the Jewish Dating Blogcarnival has appeared.
There's a carnival for ME! I've volunteered to host the next Bad History Carnival, so keep your eyes peeled for bad historians, analogies, and other ahistoricalities.
It's not technically a carnival, but Penny Richards' disability blog roundup has some great reading as usual.
And to the Harry Potter fans I've offended... tough. I'm still a serious fantasy and science fiction geek, but I was never a trekkie. I've read Star Wars books, showed up the first day for movies, played with plastic figures.... but I grew up (and I never played out the Star Wars stories with the figures: we made up our own stories). I've been to Science Fiction Conventions (but never a TrekCon). I'm sorry, I just don't get fandom; I think it's pathological and I think the fandom economy (and it is an industry, people: you are a market) is highly problematic.
