While "last post first" ( LIFO ? ) works well when you are always looking at posts, or when there are very few posts, it gets very confusing when there have been a bunch of posts since your last viewing. Most of the boards I frequent use "last post last" ( FIFO ? ), and a good number have tried it the other way and switched back.
I think it's one of those things which sounds good in theory but doent work as well in practice.
