Why is there suddenly a plethora (I love that word) of three star rated questions?

If you look on page 2 of Answers, there are only 2 or 3 questions on the page that haven't been rated.  Not that I really care one way or the other, it just struck me as strange that it seems to have suddenly started and piqued my curiosity.

Actually, there are times when I wish I could pick more than one answer as Best.  Several of you would have gotten one here.
As it is now, I'm going to give this one to Re-design, because I really like his suggestion and I think it is worthy of consideration by Instructables management.

It would be nice if we could rate them on question interest, effort and grammar.
You deserve a patch for grammatical style !

Someone clicked the rating. Sadly, the first person who clicks the rating sets value that gets weighted more heavily than any subsequent rating.

I can rate questions? Why?

The I'ble Rating System uses a weighted average.  The first new rating gets averaged against the overall mean rating of the whole site, which is basically three.

Yeah, I understand that, I was just wondering why so many more questions were getting rated when that hasn't seemed to be the case until the last day or so.

I think Orksecurity is right:  some user reading questions has decided to rate them.  A lot of us don't.
Someone's in the mood to rate questions. That's not a Bad Thing.
