Chuquet listens for the buzz.
Why? When search sites say ‘give us keywords and we’ll filter interesting stuff for you’, I never know what keywords to use to get ‘interesting’ stuff. I’d rather just see what lots of people are linking to on the basis that if several people are linking to it, it might be interesting.
How? Chuquet regularly scans several hundred feeds, and looks for common links that appear within those feeds.
Chuquet has gone out of beta.
