Bitcoin Search Engine

I'm building a search tool specifically for bitcoin resources. Not a directory of top level sites, but a real Google-type engine.

What I've included to at this point:

-Products you can buy with bitcoin (e.g. google shopping)
-Services offered for bitcoin (e.g. web development, etc...)
-Ratings & reviews (aka, yelp)
-Development tools / github projects
-Investors & Funds targeting bitcoin
-Start ups
-Markets, exchanges, and payment processors

What else would make your life easier to find bitcoin resources/lists?

Any feedback (positive or negative) please? I'd thinking of some features like people search (by name, email or btc address).

Thank you!

p.s. long time reader, first time poster, thanks for all the great community.

p.s.s. For the technical folks, I'm using nutch to crawl with a lucene back-end & some hadoop goodness. Rails/Bootstrap front end.
