Well, having just finished Tales of the Slayer, vol. 2, I dutifully went over to my GoodReads page and tagged it as only to discover that it was my 100th book read/completed this year. I know for some people that's only a drop in the bucket (my wife, for example, has probably read ten times that much for her PHD program, alone), and I'll be the first to concede that they have not all been 800 page novels, but this has been a heavier reading year for me than normal and it was nice to see that triple-digit number there.
I think that GoodReads has probably helped out with that, too. Ever since signing on it's been easier to track what I've read, when I've read it, and all the books that I've started but left sitting on the shelf unfinished. For most people, this probably sounds like it would serve no real purpose for you, but for me and my borderline OCD tendencies, it's like a constant challenge to keep reading, not get too distracted, and to go back and finish off some of those lingering books. It's oddly satisfying to be able to go on and add something as having been read, and to browse other people's reading lists, as well.
I'm pretty sure I've also commented somewhere on this blog (yeah, I looked but can't find the post) how cool it is for me to be collating all of these books and dating them in terms of when I got them, where I bought them, when I started reading them and when I finished them. Not only does this appeal to the aforementioned OCD part of my brain, it has prompted me to dig through bookshelves, boxes, memories and blog posts to establish the correct times for all of these things. In the process of doing so, I've run across a lot of cool things I forgot I had or hadn't seen in ages, or passed by blog posts that jogged some interesting memories.
