I was one of the very first round of Forum Nokia Champions in 2006. Last year (in the autumn of 2008) I was not re-selected, which is pretty understandable as I had not done anything externally visible since joining Google at that point.
Since then we actually launched Google Latitude and open sourced the Jaiku S60 client which were enough to win membership once again.
Congrats, Mika! And welcome again! :)
