I got two upvotes on [this question](http://serverfault.com/questions/485790/download-a-file-from-the-shell-when-button-click-is-required) but no rep from them. I was nowhere near the rep cap for the day, and I can't think of any other reason I wouldn't get the rep.

Why wouldn't I get rep for those upvotes?

(Note I'm sure it's calculated correctly, I'm just curious why they didn't count)
