Single? Use Twitter? Awesome.
Plenty of Tweeps is the online community where single Twitter users connect. You can search single Twitter users nearby, signal interest, and send messages to get to know people beyond their 140 character limits. It takes 30 seconds to signup, and it's free to get started.
