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 -- '#').
