Last year I was program chair of XP Days Germany. Although it was quite a success I wasn't really content with the old-fashioned process any more: submit session, review by commitee, accept or reject.
So this year's program chair Stefan Roock boldy took a new approach: Submission and review are starting from day one concurrently and - even better - any one can contribute in both activities. I'm really thrilled about that and hope it will show the superiority of the wisdom of the crowd...
Here is the CFS in English and German. Come and meet me in Hamburg, Nov 27 to 29.
