Thanks, glad you like the demo video!
The inspiration for Optimizely came out of similar frustrations when I was the Director of Analytics during the Obama campaign. We went through a long drawn-out sales process with Omniture Test & Target when all we really wanted was a short demo of the product. Hopefully we've done a good job of building a product that is easy to use and understand so we can avoid doing a 30 minute presentation to explain how it works. We're building the product I WISH we had back during the campaign.
We're actually thinking of putting together a series of short videos showcasing different features of the product similar to how Splunk does this: http://www.splunk.com/videos
Is this something you'd be interested in?
