Polls are great fun until people take them seriously ;-)

Did Adii intentionally game the poll? No, but he intentionally promoted it. It skewed the results because no one else did, thats all.

Did Woothemes gain more exposure from this? No, the people on WPTavern would mostly already be aware of them (or already become aware of them by seeing the name in the poll), and his Twitter followers already know about him/them.

Did Woothemes win some coveted prize? No, its just an unscientific poll on a blog like so many others that we all enjoy from time to time.

Did Adii do anything good? Yes, he delivered a whole bunch of traffic to WPTavern, some of whom may never have been here, and some of those might subscribe and stick around. Isn't that nice?
