I want to use something other than goodreads, but I've tried most of the others and their management of lists just isn't tolerable for me. I've tried migrating to several (and the fact that most of them allow you to import from goodreads export is awesome), but I like to have a list with the nonfiction sorted out, a list I care more about of 50-60 I consider high quality about or adjacent to what makes us tick, and a few smaller ones, and rebuilding those lists is just too brutal to accept. They're also significantly worse in terms of quality of their database of books.
Goodreads lacks some things I'd like, too. Primarily, I'd like to be able to treat a series as a first class citizen so I can provide a couple paragraphs and ratings on the series as a whole, with the individual books kicked down to a lower layer of my reading hierarchy. Also, despite allowing you to manually order your lists (my version would allow for tiers), it doesn't display that ordering when you share a list with others. Eventually I'm probably going to roll my own and set it up so I can randomly suggest some of my favorites on a page, but I haven't got around to it.
I like the idea of bookwyrm, but I think it's too much mental overhead to implement the features I want for now, and ended up not doing so.
