While I am loving a lot of the new features, I also miss the threads, when I click on a particular forum from home page, the mix of old and new is nice and exasperating at the same time. So finding an old thread is available from search but if I know how long ago it was I could just jump back a few pages of threads and be pretty sure to find it quickly.
I have found interesting old threads but it is a crap-shoot.
