If you use dating websites and you’d like to meet other atheists, there are really two options:
One is to go to a traditional site (like Match or OKCupid… anything but eHarmony, really) and search specifically for other atheists. Because of the sheer numbers, you’re bound to find other like-minded people. (Whether you’re a good match or not is a different question.)
The other option is to go to atheist-only dating sites. So far, these ventures haven’t fared as well. Maybe because the numbers never hit a tipping point or maybe because the number of men on the site vastly outnumbered the women. Those are challenges any site like that has to overcome, though.There’s now a new site that wants to give the atheist-only idea a shot. It’s called CarbonDate.Me (clever!) and it was started by folks at ThinkAtheist.
Like all new sites, it’s bound to have some initial technical problems, and its success depends almost entirely on how many people sign up (and if enough of them are women). Right now, there aren’t a lot of profiles at all. However, registration is free if your sign up before August 7th so if it’s the type of thing you might be interested in, now would be the time to check it out.
