The message bar when I get a new badge reads "You've earned the whatever badge. See your profile." If I view my profile using the "profile" link, the notification bar goes away. But if I view my profile in another way (by clicking on my username for example) the notification does not go away. Seems like both should get rid of the notification.
A single notification bar would be nice. I have had at least 2 show up, then I'm forced to go deal with it as I lose my screen real-estate - by an overtly orange bar nonetheless. I don't mind the notifications, actually I like them.
However, it would be nice if there were some options:
I like that the notifications are "sticky." I might have other reasons to peek at my profile without digging into the reason for the notification.
The notification is a good "sticky note" to remind me to check something specific. When I am done with it, I can click on the profile link or the "X" to dismiss it. I wouldn't want it inadvertently dismissed as a side effect of something else I did.
I vote to leave it the way it is.
