Agreed, sort of. I use Bookwyrm but I don't get the appeal of "social reading". I don't discuss books with others because my taste in books is lame, my opinions are usually controversial among book enthusiasts and I would rather not have people looking at what I read. Bookwyrm is also apparently much more expensive to run per user compared to most federated services so I feel bad for costing the instance admin money. But I don't want to switch to a completely offline or personal instance because I like being able to sync across multiple devices and get book recommendations from the larger instance's database.

This comment also reminds me that my reading has been paused for several months and I should get back to it.
