I'm right there with all of you. Around June 2008 I'd all but stopped reading for pleasure because 1. I was back in school and finishing up my Master's and 2. I didn't have any idea what new books/authors to try out.
I ended up joining goodreads.com to find suggestions on books to read, and my TBR list filled out to a reasonable number. And then I got a Kindle, and hooooo boy! My TBR list is overwhelming, and I'm constantly finding new books to add to the list. It almost
makes me miss having a list that had petered out.
I also have a really difficult time picking out which book to read next. I usually end up picking a series/author and read several books in a row by the same author, then debate for a bit over which author to start next. Goodreads helps me keep track of my list, but it's not good at telling me what I should read next
