I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I just saw Jessica do this, so I thought I might as well too, just in case.
When I joined BookLikes, I stayed active on my Blogspot blog and joined and began heavily using LibraryThing, but I don't consider either of those places to be great for social interaction. If BookLikes goes down, I'll probably go back to using Goodreads, although my shelves there are currently way out of date, by 406 reviews to be exact.
Hopefully none of this is necessary, since I much prefer the interaction on BookLikes to the time I spent on Goodreads, but the complete lack of communication from BL employees doesn't fill me with much hope.
