Ok, I admit it crossed my mind. The idea orbited, briefly, in a position slightly higher than 'winning the lottery' before its trajectory was destabilized by a rogue dost mote and it rejoined the Kuiper Belt.
On the other hand...
At least here, instead of scaring the girls off with my insufferable personality, ruggedly unappealing appearance, and my offensive lack of religion I'd only be scaring them off with the first two. C'est la vie.
Seriously, I heard about something described as "myspace for atheists" and thought...."I'm there." Mainly, I would love to make some atheist friends in the area (near Medina OH) because I'm surrounded by people of various degrees of religiosity and the closest I have are my brother and dad who are vague "something"-ists. Even they easily fall prey to emotionalism and magical thinking, which sucks. It would be completely awesome to meet up with a few people and hang out without having to pretend or read from a script, and maybe play some Rock Band down the line if I can either get my own system or get my brother (very atheist-friendly)to join.
Hooking up? Not entirely sure what that means. If you mean simply finding sex-partners, then no. But I'll admit the briefest moment of "wouldn't it be cool if I met some great atheist guy on here?" Didn't stick though, partially because I don't hang my hat on what-ifs and other wishful thinking (I'm here for the atheistic company overall, not to pursue Cinderella-style goofiness) and partially because I intend to move to California to pursue my career so it's probably not very wise to start a relationship in an area I have no intention of staying in. That wouldn't be very nice of me. But I covered that on my page.
Also, online relationships are indeed scary and risky. I think I was approached by a predator years ago on myspace. Claimed to be a famous skateboarder, talked online a little, talked a bit on the phone, then got what I later found out was a "booty-call" e-mail. I informed him that I do not leave the house to meet people I've never met at 2 am, especially without telling anyone, but that I was available on Friday if my brother and his GF could join us. Never got another call. Took me off his friends list. Good thing I'm the nervous, cautious type, because I only found out later that that's how some girls disappear never to be seen again.
Unfortunately, sometimes it seems like online may be the only way an atheist can meet another atheist--for any purpose. Christians have it so much easier, at least in the US. So it's not entirely out-of-the-question that an atheist signing up for an atheist community wouldn't at least entertain the idea for the briefest of moments.
