Almost 2 months ago, I mentioned cuil and how it offered up a different way to organize search results.
Since then, I've actually used to research a couple of topics... namely, Amazon Web Services tools, the Battle of Hastings, and how to generate UV light.
On the Battle of Hastings, it did a nice job since there was plenty of multimedia type stuff surrounding the topic. The left-right layout and page previews helped me zero in on some information, get a refresher on the topic, and then find a couple of places to dive in deeper.
On the technical stuff, though, it fell kind of flat. The UV light research turned up lots of links to what UV light is and how it works, but not so much on the "help, vampires are attacking and I need a weapon NOW!!" front. For the AWS tools, I basically got links back to Amazon's forums. Thanks a lot.
So. As things stand now, it's pretty much going into my webz toolbox as "the place to go instead of the library". Will be nice if it sticks around, but I can't say there'd be a huge impact if it didn't.
