Disclaimer: I'm not confusing a feature with a startup.
I love watching meteor showers.
I often forget about them!
Spacedex isn't bad, however it should be updated far more often. "2013" appears in far too many places on the site.
Also, it would be great to get email notifications.
As well as custom viewing guides based on locations - especially for the Bay Area! (Tip: The Joseph D. Grant County Park is a great location to watch meteor showers in the Bay Area of California).
