Lingomatch promotes Language Swap in select cities worldwide.

There are any number of sites where one can go to find a language partner (you’re learning Finnish, she’s learning English) via chat or Skype, but this one is set up as a social network / (hopefully?) platonic “dating” site to find a local language exchange partner. Sadly, this is limited to major cities; otherwise, I’d probably have already signed up for an exchange or four. My ESL/second language skills are getting rusty.
