Yeah me too. It's gotten to be a pretty regular daily event. Every morning, I open several windows of different posts when I first get into work (around 7 am central) and then read them each at my leisure. Usually around 730ish, the site goes into "overload" mode which I discover if I hit any links (usually to go to the next page of a thread) so I just tab through all the windows I opened previously and then wait it out after that.
I was hoping that after the maintenance performed over this past weekend this would be remedied but no go.
