noodle: the flickr preview functionality thing is a little wonky.  probably not buggy, but the way it works is weird, especially if you fly over all of the links with your mouse.since the search functionality is the core of your app, you should focus more on the search box.  its a little hidden inside things.  put the search functionality inside the central blue bar on the main page, google style.  make it clear what the users are supposed to do, and then leave the supplemental register/login stuff where it is.  imo, that is.since its tag-centric, perhaps integration with technorati?
