Here's the announcement on the Widsets blog, from my fellow colleagues (we are on the same floor) at Nokia.
I hope to write a first look type of review, if I ever get the chance and no one beats me to it. I have a whole long list of notes on it and some comments. But, you'll have to wait or harass me into doing it. :-)
Hopefully without any magic of numerology we opened the site and made 06.06.06 a unique day. We have run the site internally and with selected test groups for a while, and also already made first upgrades according to the feedback. The whole team feels excited in such a day and at the same time we commit to stay creative and fast in future as well. Please feel encouraged to contribute, and don't forget to tell your friends!
