Same here, basically. I'm not opposed to joining up with a co-founder or two (in fact, I'm actively seeking them) but I'm not going to stop working just because it's only me at-the-moment. F%!# that.
Posting here on HN; tweeting; emailing old friends, former co-workers and asking them; standing up at meetings like TriJUG, TriLUG, etc. and announcing that I'm looking for a co-founder; hitting up the recruiters who call trying to recruit me; asking other local entrepreneurs; running a "Hackers & Founders" meetup, etc., etc.
And I do have a couple of irons in the fire, including one acquaintance I've known for a while, who is in graduate school and is interested in possibly joining me once he graduates in a month or so. Also one former co-worker who may be interested. It's been a slow process, but I'm not eager to jump in bed (so to speak) with just anybody either. I'm looking for somebody who's passionate about startup-life, willing to go "balls-out" to succeed, and - ideally - has a complementary skill-set to my own.
