mileszs: I would suggest moving the tag cloud below the results.  After searching, the first thing I want to do is see the results.  The second thing I _may_ want to do is refine my search.  In fact, put it under the pagination links.  Also, only showing the top X related/refining tags, and providing a distinct link to 'Show more tags', or something like that, would improve the experience as well, in my opinion.I would also like to ignore certain services in my search.  This functionality may be available to registered users -- I didn't register (sorry!).Cool idea, though.  Would be interesting to see it also search Twitter's unofficial tags (denoted by octothorpes -- '#').
