I explored the Rollyo, including the PLCMC family of websites.
When setting up my own account, I decided to go back to horse stuff, as I am getting a little tired of librarian stuff today. Miraculously, I managed to set up my account without too much trouble, and then I added all the horse websites that I visit - which is frankly, not that many. After I finished, I read some other people's blogs about it and realized that naturally, they had all set theirs up with librarian-related interests. I probably look like a slacker.
