Rollyo is a site that lets you create a personal engine. You define the sites you trust for a domain and this way you have high-quality results. For example, John Battelle creates a searchroll for Google that includes sources like: Google Blogoscoped and Search Engine Watch. The problem is that Rollyo uses Yahoo to deliver the results.
How can you create a Rollyo for Google? Easy:
Go to Google.com.
Create a list of expert sites for a domain and copy it to the search box like this:
site:blog.outer-court.com OR site:googleblog.blogspot.com OR site:blog.searchenginewatch.com OR site:googlesystem.blogspot.com
Go to the bottom of the page and click "Search within results".
Copy the location from the address bar and bookmark it to your browser, using Google Toolbar or del.icio.us.
