There are several errors that were already reported but still are around.
First, there are recently posts with only links, well JP made a feature to do this without 'posting':

it looks nice but it doesn't work... perhaps if this thing works it would be a next giant resource.
Another thing that's still around is the bug in the buddy list.

I'm sure these were reported before but I can't find them easily cause of another problem: the lack of power of the search function. The search function seems to miss a lot of posts. For instance I can clearly remember to have read stuff or even posted on AO but can't find it again without the thread title. The search engine seems to:
a) miss a lot of things
b) not perform a search in all forums.

Like said this was probably already said, but how can someone new easily know this if the search funstion is crappy?
