One Big Library.

Attached at a link at the bottom of this entry is a dashboard widget that lets you keep a list of items from unalog right on your OS X desktop. You can see 5, 10, or 20 recent items from the feed as a whole, or for any particular user or tag. Here's an example, for the tag "xkcd":

It was pretty easy to do using Dashcode and its RSS widget template. If you want to try writing your own widget, you'll find it easier if you already know some javascript+html and have some minimal event-driven UI development background to figure out which events need to happen and when. Or you could just grab some existing widgets you like and do what they do. I'm attaching the dashboard project source for this, too, in case you want to take this one apart.

If you use unalog and OS X, give it a try!
