I have spent the last week working with the twitter search API. I have to say that I think it is a very accessible API. I was able to pick it up and start developing within the hour.  In fact I will be announcing a new twitter app/site  in partnership with @marc_meyer and @jasonbreed. So look for that announcement later today.

All in all I have to say I am amazed by how much demand twitter supports. The API allows us to query twitter aggressively.  Many people complain when twitter goes down but considering how much they are delivery through their site and API I am surprised it does not go down more often.
