I think this is a good idea. You'd hate for someone's great post about Paris not to have a Paris tag, just because they forgot to tag it.

On the other hand, this definitely needs some sort of wiki-mechanism or other way of editing. I've seen too many sites where people tag to keep track of which movies, etc. they own. I'd hate to see a post with a bunch of bad tags because we have no way of removing them.

That's an interesting idea: open tagging up to everyone to add, edit, and delete. I haven't heard of anyone doing that... the interesting side-effect would be user-generated navigation, since index pages are created for new tags.

Well, that's two votes for 'let's try it out'... I'll give it a little longer for responses before I roll anything out.

I agree with the idea of Wiki tagging. Ravikiran

If you look at any blog entry or forum post, you'll see an option to add your own tags and view other users' tags for the post.

This isn't quite what we want-- I need to add a new permission level that allows a wiki-like "everyone can edit" mode. I also want to see if I can get the author's original tags to show up in the same space...

Early feedback welcome of course.

So if more than one person enters the same tag, you get a tag-cloud effect... which is kinda neat, but I'm not sure how useful it is.

Speaking of useful, do we want community tagging on forum posts? or does it make more sense for blogs & images?

Love the idea of community taggings. It does make more sense for blogs and images, although I have run across very interesting discussions on forum posts (that can be quite helpful with regards to a particular place sometimes) that shouldn't necessarily be overlooked :)
