As much as I like BookLikes, it's always good to have some back-up options in case the site goes dark. I've been seeing a lot of blogs about joining LibraryThing lately, so it seemed fitting to post this now. I can't stand LT, but here's a few other places where I post reviews:
https://opinionsofsaturn.tumblr.com/ - In addition to my book reviews, I also post movie and video game reviews here, too! The FAQ and tags are a little outdated, but I plan on fixing them before the year is over.
https://www.goodreads.com/Exagge - I think everyone here knows what GR is, but it's definitely where I'm most active for book-related activity.
lhttps://letterboxd.com/FredGreen/ - Strictly posts movie reviews and ratings
I have no intention of joining any other websites for reviewing at this time.
