I don't know if there's an actual impending issue with BookLikes or if there's just a whole lot of panic, but either way, if you'd like to know what other online spaces I occupy...
My WordPress (felonious tongue), which is connected to my BookLikes account. I also post about popular culture (movies, tv, anime, music, etc.).
I have Facebook, Twitter, and Tumblr accounts, but honestly have not been using them with any regularity.
For fannish purposes, I still maintain my livejournal and dreamwidth accounts, though mostly I post only the occasional fic rec now.
My Twitter, Tumblr, livejournal, and dreamwidth accounts are all under the username "eevilalice," same as here.
