Hello fellow bloggers!
I have no experienced Rollyo and found that it could be useful as a librarian. You could create a Searchroll for the sites you most frequent and be able to easily search those sites on a daily basis without having to go to each site. I believe if I am comparingi Rollyo to Delicious, I prefer a Searchrolls to tags. I created a Books, Books, Books, search roll that allows you to simply search booklists and other review sites for books you might be interested in finding out more about before you read it, or put it in your library. Let me know what you thought about Rollyo.
