I'm here looking for basically two things:
New people to hang out with, in the categories of "people interested in RPGs/board gaming who're in my local area" and "people who need a canoeing buddy".
Polyamorous dating--my wife and I are in an open marriage, and in particular I'm of a mindset that says that love only grows when its shared more widely.
For the latter, I'm open to a lot of different types of people, but I do ask two things:
I'm serious when I want someone who's a friend as well as a lover-- I need to be able to talk to you about something other than the moment. And there should be something about you that's different or unique enough to catch my attention--being a computer guy, I deal with enough bland homogenized stuff all day, I like my friends and/or lovers to have something eclectic about them.
Why OKCupid? This is one of the few dating sites that is supportive of the open/poly lifestyle--it's the only middle ground I've found between the sleazy mostly-scam "adult" dating sites and the typical makes-assumptions-about-your-single-status sites.
I stalk people repeatedly all the time on here. I have trouble attaching screen names to personalities until I've seen 'em a few times, and I also tend to start looking at Quiver results on my Droid and then never get around to messaging them until a few days later.
Related to that, I have a habit of taking a quickmatch or quiver result and randomly clicking on people in the "similar people" sidebar. This is why I appear to be stalking a lot of truly random people.
I am large, bearded, and melodious.
One of these days I need to put some pictures back up, but discretion was a little more important to me there for a bit. The current profile pic is about how majestic my mane is right now.
Music, I like anything. This is almost literally true--I can name something from almost any genre that I like. I'm especially partial these days to Counting Crows, Foo Fighters, Weezer, De La Soul, and my collection of musicals and classical. That said, my in-car rotation is heavy on Ani DiFranco, Dar Williams, Gorillaz, and VNV Nation.
Movies, I'm a little more partial to action and comedy than anything else, but I like intelligent action. 2 Fast 2 Furious is right out--I'm more a fan of Indiana Jones, The Lord of the Rings, that sort of thing. I think we're living in a Golden Age of superhero movies. I can't stand films with no discernible climax or plot arc, but I love a good drama.
Books? I can't even begin here. The last things I read were by Lois McMaster Bujold, Terry Pratchett, Maeve Binchy, and George R.R. Martin (yes, I'm the last geek in the world to start A Game of Thrones, apparently), and that guy who I can't spell without a reference who wrote Night Watch. Sergei Lushenenko? Can't remember the last name. I literally read anything I can get my hands on--I devour books.
I find myself being "in with friends" a lot lately, too. Even once everyone's scattered to the four winds, you can maintain a surprising amount of camaraderie with a voice chat conference call and some online games.
I secretly feel a little twinge of guilt when I check out the profile of someone who visited mine and find "Christianity and very serious" or "I'm not interested if you're not single", as though I were somehow deliberately wasting their time.
You're interested in finding a new board gaming or RPG gaming group in my area, especially if you're interested in something more adventure-y than drama-y. As much as I love narrativist games, some days you just need a pack of mooks and an absurdly high attack bonus.
You're interested in some hiking, canoeing, or camping. The idea of becoming friends and eventually doing something like a 3-day canoe camping trip down the Delaware is pretty cool.
Any combination of the above, for that matter.
Oh, also: if your "Most private thing" section contains a variant on "No" or "Why would I put something private here?!", then dock yourself a few points. Then get over yourself and put a funny anecdote in there. =P
