Just spent some time reading about RSS, which was new to me. Looks real interesting. I've wanted a client-side version of the functionality spyonit.com used to offer ever since I first saw spyonit. It seems that RSS could be that someday, if it moves beyond bloggers, eh?

NetNewsWhatever looks like just the app I want (except the Mac bit). But the logical conclusion is, as you say, dynamic bookmarks. I see a project or two underway to write an RSS Mozilla sidebar. That'd do the trick. Doesn't seem like any are done yet tho.

Guess I'll browse around some more and look for Windows apps.
