Plum is similar to Kaboodle and Stylehive in that it is a social bookmarking site that allows users to add a lot of metadata about bookmarks (including images). Bookmarked items can tagged and be added to a public, private or shared “collection” (there are a number of defaul collections and more can be added).

One key way that Plum is different than other bookmarking site is that it allows users to bookmark items on their computer, not just on the web. A file that is open in certain desktop applications (things like photos, power point presentations, iTunes playlists, address book entries, email, etc) can be added to Plum by clicking a button on the Plummer, a small downloadable application for Windows or Mac. See the last screen shot below for a look at the Plummer.

Gee...projects and local resource tagging!  How are we to ever keep up?
