It’s really nice! Great UI, not particularly buggy, feels great on the user end. Honestly pretty darn polished for a fediverse platform I’d never heard of until like a week ago. Also, the flagship instance (where I’m at) seems to be mostly reviews in Chinese, and it’s always nice to see parts of the fediverse that aren’t dominated by English. I am somewhat confused by the difference between a comment and a review, since both terms are used but everything seems to wind up in the same place? That said, I also haven’t tried very hard to figure it out either.
Having used BookWyrm and NeoDB, it’s definitely very comparable to GoodReads vs IMDB, at least in terms of interface/user experience/aesthetics/etc. BookWyrm being specifically for books, it has a ton of fields that wouldn’t be applicable to anything else, i.e. “publisher”, " ISBN". It can pull data automatically from some outside book databases. NeoDB seems able to do that same thing, except for any kind of media. Not sure where all they’re pulling the data from. They also seem to have fields for just about anything, from tracklist to director to author.
