I had my first play with WolframAlpha this morning. I was watching the launch on justin.tv and saw the search url people we using. By doing this I got around the opening soon window ... Hope that's ok. Anyway very cool. Sorry for the poor video really just recording my play. The big thing is knowing what you can do and how to approach searching. Was very fast until they started load testing and then things started timing out. Cool as a first experience though.
