Comet and tagging
It's really great that Comet supports tagging. It's a huge lack in Typepad currently. Right now, though, the implementation is lacking, IMHO.
The most basic problem (and many other people have pointed this out) is that tags right now are only useful for organizing stuff within one asset category in one blog. So, I can use a tag to find stuff in my own blog entries, or my own albums, or books-but not all stuff with a tag. Obviously I would like to be able to do that.
If I'm looking at someone else's site, I can use tags to find stuff, but again, only within one category.
The biggest need, though, is to be able to connect my tagbase with the tagcloud of the Comet community at large. If I tag something "v-mars" I want to be able to see if anyone else has blogged (or commented, or whatever) with that tag.
While I'm on the subject of tagging. I think tagging should apply to everything in Comet: blog entries, media assets, collections, profiles, links (if they start getting treated as assets, which I think was a feature request) everything. Even comments. With comments, I think inheriting the tags of the post the comment is on would be a good start, but you should also be able to add tags (or remove, possibly... interesting issues of ownership there) to your comments.
Once you connect the tagbases of all the users, you can then create a tagcloud like you see on flickr or del.icio.us. But maybe do something more interesting with it. Differentiate it, so Comet doesn't start to feel like "flickr for blogging" (Technorati has that space.) Show the most popular tags, but also show the most unique, the new emerging ones, ones that are becoming passe, stuff like that.
