A dream feature, not something I seriously expect the people at Tricycle to work on: I want an option for a voluntary "blind mode" in preferences. People in blind mode wouldn't be able to see the poster of a comment's name or the comment's current karma score until they either voted up, voted down, or clicked a new "vote neutral" button; after voting, the poster and karma score would be revealed but the vote could not be changed.

Reason: I find myself slightly tempted to vote up the articles of people who voted up my articles as a form of reciprocity, or else to vote up the articles of people who didn't vote up my articles to prove I'm not doing that. I'm sure on an unconscious level the temptation is much worse. Plus this would solve the information cascades problem.
