Goog is much better than Twitter at serving relevant content to me. Are they so far ahead of the game that no one else can join? The #diabetes hash at Twitter has a lot of not-so-relevant material to weed through. The same search at Goog gets some pretty relevant material in front of me. If Twitter does make some search changes, won't users abuse the ability to capture the search queries? Great article though and I agree with the writer, it is going to be a great show to watch.
