Check out BabelWith.Me. It's a free web-based chat room except it automatically translates conversations into 45 languages! That's real time communications without language barriers.
Each conversation has a unique URL so you can invite others to join the discussion. You can also share the discussion via Twitter, Facebook or email.
Now you can hold conversations with people all over the world and actually understand what they are saying. Pretty amazing! Kudos to the creators of BabelWith.Me.
