These 3254 people voting for the Linux client might encompass the whole of the future user base of the client.

Linux users traditionally have been more involved in a community, so it's entirely conceivable that next to 100% of potential uTorrent Linux users have taken the opportunity to vote whereas only a fraction of a percent of utorrent's total user base voted for the second highest rated feature.

I would probably not use a poll like this to direct the future planning of my product.
