That RIM was more willing to "kick" this company to the curb and serve them a lawsuit, rather than perhaps acquiring an innovative team and hot messaging platform, is indication that this company simply doesn't "get it". RIM is absolutely dead meat if getting sued is your reward for building apps for Playbook or Blackberry.
I've never tried Kik, but I know several people who signed up when it first came out, but then stopped using it after a while because they realized there weren't that many other people using it.
3-letter pronouncable dot com. That's worth a lot.
