One feature that I can see possibly being valuable here is the ability to filer, prioritize, or otherwise throttle the notifications.
An example would be my usage of Google Reader; there's a Chrome app[1] that shows notifications for new items, but I haven't been under 1000 new items in years ("1000+" is as high as it tracks). Yes, I have many feeds I need to prune out, but even then, I may get upwards of 100 new items a day in my reader and I sure as heck don't care about them all. I really just care about items from a few select sources, but without a way to filter out the noise it's useless.
I'm not sure if that use-case would be very common for your app, although there's times when I make a popular FB post that I tend to ignore the notifications once they get past about 10.
