I recently discovered Bookwyrm and am really liking it. It's not quite as full-featured as The Storygraph or Goodreads but it covers all of the most important functionalities and it's federated which I appreciate. Something that it is missing Vs either The Storygraph or Goodreads at the moment is volume of reviews (ie. Volume of users.) However, your review won't get lost in the sea so much and I've found that it's been quite easy to find readers with similar interests.
Anyway, who here is using Bookwyrm? What's your account so we can all follow each other?
