I like it. It will no doubt be refined as more people learn. It will be interesting to see how it holds up.
On a side note, I think a majority of the arguments I've read against it aren't very good ones. I see most of them boiling down to, "it's different, I don't want to have to learn a new language". This is what I said when I was learning standard music notation. I can see the issue of its anglo-centricness, but even that is a minor detail. One doesn't need to understand the words "above" or "below" to be able to associate the symbols with the notes.
I don't think a fair critique can come out of a quick glance at the hummingbird website. I'd be more interested to hear what people say after a few months of working with it.
