Rollyo personalized search

Walt Mossberg writes about the interesting Rollyo search engine. It's kind of like http://del.icio.us, only you search across a space of web sites.

For example, search a "Microsoft"-themed search roll on "Speech Recognition" and I get only 197 hits--far fewer than the 6M hits that a similar search on Google Microsoft gives. (The whole Google gives more than 60M). And all of the hits appear directly relevant. They should be: they're only from sites that have been hand-selected for this Rollyo roll.

The extra-cool factor is how anybody can publish their own roll of sites. So if you're an expert in a particular subject and you have your list of bookmarks that you'd ordinarily consult, you can now share that list with the world.
