How are you handling category and tags?
We I don't know of any good way to handle these :-( On our site (NewsPeeps.com) we don't use categories, just tags. The problem I have with categories is that they are too transitory. For example Silverlight
is a category on DotNetShoutout, but didn't even exist untill a couple of years ago and who knows if it will be used in 5 years? (Speaking here of the name, not the technology).
For tags, I like how StackOverflow handles tags, any item (story, or in their case question) can have up to 5 tags and anyone with sufficent privilages (reputation) can edit the tags after the item is posted.
It would be great if there were a super easy way to changes the tags for a story after it is added to the site. Drag the tag onto the story and drop it perhaps?? Unfortunately I believe this is the only realistic way to get good tags since it is extremely
difficult for a proigram to analyse the content of a web page and decide on the appropriate tags.
Anyway that's my 2 cents worth ;-)
