Paradox Hah! I can't help being driven! =)
As for the several-badges-in-a-row thing, I noticed that happened after the rep system was over-hauled, and the system recalculated a lot of what people earned--so, for example, the Active-->Hyperactive badge was new, but a lot of people were granted it retroactively, and so they received 11 badges in a row or something.
I should have about 13 legit Good Comment badges, it's just when the rep was redone, a bunch got handled as a batch.
I am, however, sort of missing two badges, and I know one of them is Dedicated Updater, which I should have earned today, but didn't. I got the 25 rep for downloading the update (7,132+25=7,137), but not the 100 for 10 in a row. And when I go to the me/badges page, I'm listed as having 47 badges but when you manually count the "Your Count" column, only 45 are credited.
