Searching Twitter

I looked at a few of the search choices.
It seems to depend on what you are searching for as to how good the results are. My first search was for comedian Dai Henwood which I found easily on both Tweep Sweep and Twitter Search.
When I searched for Rove the result was good in Tweet Sweep as Rove has a profile set up, but in Twitter I needed to put his full name otherwise there were too many results. (It was looking in the content of people's tweets rather than profiles).
I didn't like the look of the grid in Tweet Grid when I looked at Trending Topics - I found it too busy. Monniter was a bit strange to look at too.
Searching for a topic worked well in all the searches I attempted to find 'The Lovely Bones'.
I think I'd stick to Twitter's own search.
