I don't bother with a TBR list. There is always going to be something out there I'll want to read, I don't need to regiment it.
I buy books that sound interesting if they are cheap enough, use the library a LOT, and basically read on whim, whatever feels right at the time. I keep a good selection on my readers, so I'm not likely to have trouble coming up with a book I'll feel like reading.
A friend did get me to track this year what I've read via Goodreads, which may be kind of useful so that I can remember down the road if I've read something before or not, given my memory is not what it was. I think I'll keep that up. But I re-read often as well, so it's not all that critical.
