Well, they've got plenty of Wikipedia results in their search.
The debut of Cuil (pronounced 'cool' they say)
When it can hit Wikipedia, Cuil does fine.
Clicking on them found Cuil a little too hot to handle. "Due to overwhelming interest, our Cuil servers are running a bit hot right now. The search engine is momentarily unavailable as we add more capacity," said the message that returned instead of results.
Danny Sullivan said the site runs off two datacenters, with a thousand 8-CPU servers apparently handling the index, and another 280 delivering results. At press time, it wasn't enough to handle the buzz from coverage at places like TechCrunch and GigaOm.
Webmasters who want Cuil to tap their pages should be seeing a crawler called Twiceler hitting their sites. Sounds like someone at Cuil might be a fan of Dr. Seuss' 'The Lorax', which featured an environment-trashing executive called Onceler as its antagonist.
The real test for Cuil when it comes back will be how well it handles the niche queries people make all the time, expecting a solid result from very few words. That's how Google built its dominance in search; people assume search works this way, and they will be happy with Cuil if it does.
