I've build a lot of Rollyo Search Rolls. Seems an ideal way for educators to create a 'closed' set of resources for their students without spoon feeding them each site. You can re-inforce search skills with student safe, pre-selected sites.
Here are the searchrolls developed for my 21st Century Information Fluency Project:
Website Evaluation: http://rollyo.com/21cif/website_evaluation/
The Digital Information Fluency Investigator: http://rollyo.com/21cif/dif_investigator/
Library Media Advocacy http://rollyo.com/21cif/library_media_advocacy/
Copyright and Fair Use: http://rollyo.com/21cif/copyright_fair_use/
Search the 21st Century Information Fluency Project: http://rollyo.com/21cif/21cif_site_search/
Here's a good search engine overview of Rollyo: http://blog.searchenginewatch.com/blog/060203-000505
I want to explore a new tool mentioned by Searchenginewatch: http://www.pubsub.com/
I'll have to play with it!
