blekko is a better way to search the web by using slashtags.
I don’t know what that tells you, but the name and the tagline for this new search engine conjure up some pretty nasty images for me, and tell me nothing about the service. Blekko is a nonsense word, and you may think one invented word is as good as another, but Blekko sounds like something you need to clean up. And ‘slashing the web’. I dunno, that sounds nasty. Luckily they go on to explain…
slashtags search only the sites you want and cut out the spam sites. use friends, experts, community or your own slashtags to slash in what you want and slash out what you don’t.
Web Seer is a fascinating tool that lets you explore what questions people are typing into Google, and compare it to other questions to see where they overlap. Admittedly, I can’t think of a real world use for this, but it’s fun to play with. If you find an interesting comparison, please leave a link in the comments!
