First, it's slow as molasses. Now, I know it's day one, and everyone's trying it out, but it doesn't even come close to Google on response time.
Second, there's just not enough information on the first page of results. When I search, I want a clear, concise list of results with no more content than necessary to determine if the hit is relevant. Not only does cuil provide too much content in the results, but it's not often relevant.
Third, Google is a one-stop shop. I get web, news, images, video, etc.
Let's take an example. My search term is "Cobb County Police Scanner".
- Google: Blink of an eye. To short to notice.
- cuil: 2.5sec for the page to finish rendering
- Google: 10 results, with all ten relating to either a Cobb County Police Scanner, or the Cobb County Police.
- cuil: 11 results. None were relevant. The first hit looked relevant, but was a keyword harvester and redirected me to an adult site (gives new meaning to Google's "I'm Feeling Lucky"). The rest of the hits were a mix of offline servers, keyword harvesters, and porn sites. cuil was totally useless.
- Google: After my web search, I clicked on over to images. About half of the first 21 hits had to do with Cobb County Police, and the first two hits were very relevant pictures of the Cobb 911 call center.
- cuil: No image search
- Google: Next, I headed over to news. The first hit was a dud, but about 3/4 of the remaining hits were relevant, and one even had to do with the City of Marietta's recent radio purchase - very relevant.
- cuil: Crickets
- Google: Shopping was a bust - no hits - but there were a bunch of ads on the far right that would have gotten what I wanted if I were in the market for a police scanner.
- cuil: Nada.
