Facebook Places has gone live in the UK. It lit up in Japan a few days ago as well. No love for Canada or many other countries yet. Still, even in locations where Facebook places has launched, it doesn't seem to have slowed down FourSquare or Gowalla at all.
Is Facebook Places available where you are? Are you using it? If so, let us know how it's been working for you, if not, tell us what's kept you away.
