Downvotes on questions are free. This was done in an attempt to encourage more people to vote on questions, and so far, it appears to be working.
Downvotes on answers still cost you -1 rep point, just as you expected.
This is covered in the FAQ, where it explains how to gain and lose reputation:
The primary way to gain reputation is by posting good questions and useful answers. Your peers will vote on your posts, and those votes will cause you to gain (or, in rare cases, lose) reputation:
- answer is voted up +10
- question is voted up +5
- answer is accepted +15 (+2 to acceptor)
- question is voted down -2
- answer is voted down -2 (-1 to voter)
Note the lack of
(-1 to voter) next to the "question is voted down" scenario.
