Joined GoodReads and added a whack of books to my library. It’s almost like a game. One author leads to another and friends’ libraries remind me of more books I’ve read. Very good bit of design to make the user experience so easy and addictive.

I love GoodReads so much… have you joined any groups yet? There are a lot of book clubs you can join ( I feel like it’s a good motivation to keep reading when things get hectic in my life)
No groups yet. I’ve been too busy building my library. But I’ll take a look for some. Any recommendations?
