Del.icio.us Searchrolls ?

I created a RollYo search log called "Dashboard Dev". It's pretty neat and does help a lot in focusing the searches towards dashboard development topics.
Of course Apple's site (or MacDevCenter's for that matter) only have a couple of pages on something like Dashboard, so you don't necessarily have to search those pages, just know the links.
Maybe a mashup of del.icio.us and RollYo would solve the "problem": del.icio.us for the hard links by tag and RollYo for the links within sites that have more and disperse information.
