YEAH!!! This has become my favorite phrase. I log on to Blog Explosion and click away. It has become less about the earning of credits for me, and more about seeing how many of those prized mystery credits I can win! And I'm facinated that I can just rack them up one day, and the next I will hardly get any.
The highest I've hit so far is 25. I don't know what kind of lucky charm or silly dance you have to do to hit 100 - if you've done it let me know!
