As Ray says, the New Posts is really dissorientating.
I'm surprised anyone uses it, but this thread obviously proves I am wrong.
I think we experimented with the New Posts setting a few days after going live - and by changing it to also isplay read posts broke something else IIRC - it's mentioned in a very early thread in Feedback somewhere - I'll see if i can find it
Well I use the 'new posts' all the time and 'todays posts' only occasionally. I guess it depends on the frequency you visit like Phil said earlier in the thread.
