Sreshta.bg (means “meeting”, “dating”, in Bulgarian) is one of the sites, created and developed by my long-time friend and colleague, Mitko Ganchev. It may be worth visiting, esp. if you speak Bulgarian and want to make friends.
It’s a dating site, and what I like about it is the interface. I’ve registered a long time ago to see how it’s working, and it’s cool. What amazes me, though, is the number of people who regularly visit it, and participate in the community there.
People actually meet not only virtually, but live, too. And, as far as I know, there’s at least one couple who got married through the site.
