Hi Monica! Sorry for the delay in responding but I was on vacation. Good to see you here, as I always enjoyed your posts at the library.
Jane, I did post a note on the google group site about checking out EYB. (If anyone wants that link, let me know.)
Debkellie, what I liked about the 101 Cookbooks site was that the members were pretty closely aligned taste-wise, but not so much so that things got boring. As a result, I found lots of new cookbooks and new recipes from my old cookbooks through that site. People would take the time to do some really detailed recipe reviews, which were very helpful.
In terms of functionality and how it compares to EYB, the part that I miss the most is that you could "like" recipe or cookbook reviews and comment or ask questions directly about them. AND, you would receive notifications, so you wouldn't miss anything. Part of the reason that I write notes is for my own recall, but I also do it to help others, so I really liked the interactive features of the library.
