I really like the fact that there were 2 different badges for participants and winners last time, because even participating is noteworthy. I think we should keep that, for whatever my opinion's worth. *shrugs*
I think all of these ideas are great! 10K in 30 days is a good number since I'm taking care of two littles. I'll also participate in the official one, but I loved the ideas of the two badges from last year. It made me feel appreciated even though I didn't win.
