In addition what you've said,
I generally downvote
- entire off-topic threads (especially the "can you guys be my search engine" kind, or "can you be my man" -- I like to -- the answers first, cause the encourage posting to SOPW instead of issuing a `man command')
- nodes getting off topic (like the beginning of a flamefest, or simply a discussion of how X really works)
- lazy nodes (asking questions easily answered by "perldoc -f", especially by monks who how to use perldoc f -- it's not that they can't understand the manual, but they demand it be recited to them )
- preechy nodes (the kind merlyn is known to write)
- hypocritical nodes (merlyn is also known to write some of these, not practicing what he preeches)
- ignore nodes (where a poster chooses to ignore the answers, continually reposts code he gets as answers untill the community essentialy writes his code)
- ignorant nodes (where a monk,
convinced he is right,
continually argues a point disproved in
the node he first replied to,
all the while getting more frustruated and rude,
dragging it out 10 nodes deep,
and in the end not even acknowledging he was wrong,
much less apologizing for being rude)
- ideas I dislike (for example artist often comes up with feature suggestions that just don't make sense to me)
- dumb jokes (especially those presented as answers to legitimate questions -- especially those of the religious war genre)
Don't be fooled though, I do spend most of my votes ++ing good questions and answers (it's a good thing I got lots of them).
