For me voting on questions is much less important than voting on answers.
If you have a question, you have it, period! It doesn't matter if it was upvoted by others or not. The reason you ask the question and the reason people come to Stack Overflow is to find the best answer. I rarely vote on questions, I normally vote on answers.
Jeff says voting on answers is so sexy, that people will still do it (well I do). The idea is to encourage voting on questions.
Following this thread and watching the number of upvotes, it looks like many people think it is a good idea to vote on questions, but so few actually do it. Why?
Joel mentions (no, not Spolsky. The one who matters: Coehoorn) that shifting rep from questioners to answerers is a bad thing. I assume he refers to the discussion of gaining rep with meaningless questions.
- Shall we encourage gaining responsibility on SOFU by asking questions?
- Shall we encourage voting on questions?
- Does the new electorate badge solves the problem, discussed in Why-does-noone-vote-for-Qs?
- Is it actually a problem (it's from August 2008. Maybe you changed your opinion now)?
- Does the badge need more fine-tuning beyond the clarification of the description?
