Goodreads
I find that for some of the books that I've read, mostly when it comes to fiction, a complete entry seems a bit much. My goal of writing up these entries has always been about capturing notes, since I'd say the majority of what I read is non-fiction. While I have reviewed fiction books I've read in the past, most of the time a short summary and rating would be better to capture my feelings should someone ask me what I thought about a book I'd read some time ago. As such a few months ago I signed up for Goodreads. I'm using it to its full potential but have found it useful.
