As I don't care much about the social network aspect, I would use a competitor that offers better functionality.
Unfortunately library thing's homepage makes it seem like it's not updated for a few years, which makes me wonder if it's worth migrating for a platform that might not be actively maintained anymore.
They're actively maintained and I get newsletters and so on from them.
They thing is, on another level: they're done. They offer excellent cataloguing and the ability to share your reviews and so on and so forth. What more do they need to add? A visual refresh every few years? At this point I'd rather they spend the money their customers pay them on keeping things running, not adding crap no-one cares about, surveillance capitalism anti-features, or whatever.
