I'm going to go ahead and give you my feedback, since everything else here is nonsense crap.
I think it's a great idea. I've definitely wanted something of this sort for a while now. A notification system that alerts me when someone has written on my facebook wall, messaged me on meebo, replied to my HN comment/submission, posted a blog post, etc - a consolidated system. You should start integrating it with more services and give users the option the to pick and choose which ones they want to use your service for. I'm not quite sure how feasible that is from a technical standpoint, but from a consumer's point of view, that flexibility to hook my various services into a consolidated notification system would be awesome.
That's similar to what I had in mind. In order for it to become reality, as you point out, more services need to support it (right now, we just have to wait for the website owner to add support but soon, there'll be a way for users to add support for websites). Another important component is a log that persistently stores all the notifications you receive so that you can go back and check out all your history.

Wave requires that the services integrate Wave to begin with. This is a very high barrier. Building a notification service that binds to the various APIS is much more feasible in the near-term, regardless of the fact that the human effort needed makes it problematic to scale to a very large number of services.

Good start.
