As you've probably noticed, the forums changed the way threads and forum are marked as read not too long ago. Previously, we used a cookie-based system that marked everything as read if you were inactive for a specific amount of time. We switched to a system that stores data about what you've read and not read in the database, which tends to give more accurate results, but it also means nothing is marked as read automatically. This is a good thing for some, and a bad thing for some.
So you've had a while to try out the new method. Which method do you prefer?
