In the run-up to the T-Mobile G1 launch, I confidently predicted that the launch would coincide with the relaunch of Google's Jaiku service, which has been closed since Google acquired it. I noted how Jaiku could be the "killer app" for Android, providing location-based services with Twitter functionality and GMaps integration.
Well, here we are in the second week of November, and my prediction was wrong, wrong, wrong. Too bad. Google, get it together! Why don't you listen to me?
