I have! Although to be honest I haven't given either of them a very fair shot since the UI and complexity are a pretty quick turn-off for me personally. It's hard to compete with the established community of either site though — maybe I'll figure out a way to integrate with one or both of them eventually so people have the option of keeping things in sync between Roosevelt and elsewhere.

Another nice-looking solution I've been trying out is Readng: https://beta.readng.co

I've been working on a super simple Goodreads alternative off and on for the past year or two since I frankly can't stand the Goodreads UI. There's not much to it yet other than personal library management, but it's good enough that I already use it myself to track books I've read or want to read.
