Give simple, clever webapp #mom the phone number of that special someone who worries about you (e.g., your mom), connect it with your Foursquare account, and then tag any notification-worthy Foursquare check-in with #mom—say when you land at that far-flung airport. The service will place a call or send a text to your loved one letting her know you made it safely. Brilliant.
