There's a startup idea... give me concentrated data collected from various places on the internet (Reddit, YC, Digg, Del.icio.us, etc...) on a given topic. That's really what I want to see when I search for things like nginx, mod_wsgi, git, etc...
My little brain tells me this doesn't exist yet... but surely correct me if I am wrong :) For the record I am talking about the entire interweb (as we know it through popular "social" websites like those aforementioned) not just entering the git tag into delicious.
