I am not really enthusiastic about the poll procedure as well as the result. First of all I don’t understand why the poll was open only for 2 days within the week and not for longer including the weekend (what IMHO would bring more votes). I think that 2.600 votes are not representative for the WordPress community.
If you look at the top four, you’ll see that they are within a range of only 3%. The winning design represents the opinion of only 18%, while 82% prefer other designs (16% voted for the current).
I would appreciate a second poll with only the top four designs and hopefully much more votes.
