Wild IIlusions: 5 startups experiments I like to try

Startups or applications?<p>Scanning the list I see twitter, bit.ly tags, and firefox plugin.<p>These might be experiments in creating products but I don't see any concrete businesses.

#2 and #5 sound like they might actually have some revenue potential, but a startup based on a "Firefox plug-in to provide real time analytics for your links"? That sounds like a neat side-project, but I can't imagine how to found a company around that.

Real time link analytics seems like a great idea. It would be neat to open a chat box on the corner of the page with someone who was using the site in a weird way, and start talking to them about what they were hoping for.
