Trust me, it will pass. Full disclosure - I've been here since a couple days before we went live, and spent time, on and off, for about three weeks before that on a "beta" version Chris put up, so I've had more time than most of you (any of you!) to get up the learning curve. But it gets easier; things just work, when you learn how they work.
Further to donaldorc's comment about the blue "new post" markers - I'm still seeing the same behavior as before/right along. If you don't refresh the page... if you just switch to another tab or another browser window, and come back a bit (or four hours) later, the "Unread" link at the top will indicate how many unread posts there are, but there are no blue dots showing. If you refresh/reload the page, they appear.
In other words, the "Unread" indicator is being live-updated, even with the page in the background - but the rest of the page is not updated until you reload it.
