Frites N Meats is a food truck
They have a website:
fritesnmeats.com
Check it out on your smartphone
and you'll see something like this...
Looks like they are parked in Midtown Manhattan!
After lunch, Mr Frites N Meats
sends a tweet that they are #closed
After driving down to Union Square, 
they are #open once again!
And their site is updated accordingly.
Frites N Meats customers always know how to find them.
Just by bookmarking their site on an Android or BlackBerry...
Or adding to homescreen
for iPhone users
The mobile site also has:
Their full menu
Their blog
A direct feedback feature
Tap to call & directions
And more
With Mobile Meteor, you can reach a much wider audience: your customers just go to your site from their phone to find you. Even if they are not on Twitter.
