I would expect at least one feature that influences the links that non-pro users don't have. At the most basic this could mean having two votes per upvote instead of one. It would be much more attractive if it were something a little more complex.
Also, maybe a link to my portfolio or website posted on a special page that randomizes the order of the links every visit, or every day, or week, or something.
I'd be willing to pay $20 a year, regardless of what features it came with.
