Well the winner is JQuery, but not in a too wide margin from MooTools at the back, at least not as i thought it would be.
I personally voted for JQuery at that time, but since i switch frameworks depanding on the project nesecities, i think my vote is divided equally by MooTools and JQuery. Dojo was well at the back with only 2 (!!) votes and a close to 0% of vote share, kind of a surprise to me, i was really impressed by Dojo and was considering using it, or at least benchin’ it out a little bit.
You're seeing this error because I think it is funny.
