I hope it will eventually be a one stop shop for your notification needs!
Its pretty limited right now, but it pushes via Prowl:
twitter trends (with great descriptions from from Brizzly)
shipping notifications (UPS and USPS)
A few things on my to-do list:
- generic rss feed notification
commercial airline flight info notification
sport score notification
There's not much to see until you sign up (user interface is not my strong point)... but registration is easy.
Just put in your email and a username and you'll get a confirmation number.
If anyone has any suggestions for improvements or additional features, let me know here or on the AutoNote forums.
