When idling on the site, it's very common to see "1 new question with activity". It's a nice feature, all web 2.1ish. Awesome.
But when the questions aren't sorted by activity, it's a little misleading. It only shows up when someone posts a new question, and its text should probably be updated to reflect the actual change in the state of the system.
I'm debating whether this is considered bug or feature request. I kind of feel it's a bug, just because I'd consider it a mistake. At the same time, it's not exactly a behavioral symptom which makes me feel it's not a bug.
