Ok, so having tried the app — I won't actually use it until there is a "quiet hours" setting. Notifo got that perfectly right: there are certain hours where I do not want to be interrupted by notification sounds from the service (but I might want to keep other sounds on).
I like the idea of unified notifications, but ultimately you have the chicken-egg problem, and for that you need to find an entry point. I'm working on the same problem and whoever solves it, it will create some great value. Can't wait until notifications get detached from email.
Push notifications are a great way to consume time-sensitive information, like price/airfare,
sports, stocks, app reviews, etc. Airgram makes it dead-simple to deliver these alerts <i>without</i>
having to build your own app, so that you can focus on building interesting services.<p>Give it a spin! <a href="http://www.airgramapp.com" rel="nofollow">http://www.airgramapp.com</a><p>"I think notifications will become the primary way that we consume on the mobile device and may be

I am really skeptical (though I'd be more than happy to see someone prove me wrong) about these "framework" apps, that doesn't actualy do anything by itself, except to provide an API of some sort for others to take advantage of. They reminds me of those obscure ActiveX plugins (3D model viewers, etc) that sites make you install. I am usually somewhat hesitant about getting them on my computer unless a see great value (eg growl), but I suppose I'll be even less willing to have these on my iPhone, as an app that sits somewhere on my home screen. My users might feel differently about this, but it certainly would be very difficult for me to explain to them what is it that they are installing and the experience could become quite confusing.
I like this. I do think my phone is starting to become a bit too noisy though (too many text messages that start being more like email) and I am not sure how to keep it all organized. Perhaps you guys can help.
Have you figured out how could a website determine if your app is installed? It'd be cute to have a reddit style notification when people reply to your comments in a forum etc.
