Thing 12 -- Roll Your Own Search Engine

I explored Rollyo and created a "Digital Scrapbooking" searchroll and added it to a combination Digital Scrapbooking, Celebrity Gossip, and Health searchroll at bottom of my sidebar. I can see some uses for this in an educational setting, if a teacher, for example only wanted her students to search a specific set of sites, or if I wanted to see other sites that similarly tagged searchrolls might include, but, for the most part, it just seemed to add another layer of stuff to manage.
