From what I’ve seen, some of my users don’t really understand what notifications mean. For example, seeing this:

What does this mean?
I think there’s a lot to improve in the notification UI. Imho Facebook is a good example here. Their notification messages are very clear. Imho StackExchange notification system is ok, too.
