Classifieds with Google Base

Firstly, my apologies (to no one in particular) for the looong hiatus . Sheer laziness. Anyways, on to the main topic - did you know such a thing existed- Google Base ? It's a place to post/search for classifieds of all kinds. Yes - all kinds. Been discovering quite a few low profile changes with the goog goodies. The bookmarks for example - they now let you bookmark like delicious does, while giving you the choice of keeping bookmarks private or sharing them. Real cool.
