Amazon Kindle Store. As I said on our other blog, Geek Twins, I mainly did because I wanted to bring Dead Links under control. A few years ago, I posted Dead Links on another website as a free PDF. I recently discovered it's been spread like wildfire, but not always in places and forms I wanted it to be. But one place I'm glad to see it ended up is on Goodreads.
I discovered that four different people apparently added Dead Links as an entry on Goodreads. It's been given four stars, and one of them wrote some nice comments. I'm working to edit the Goodreads entry to bring it up to date, but I have to get librarian status. Anyway, if you're on Goodreads, check it out.
