The location-based services are evolving today. Foursquare lets you tell friends and businesses where you are. But today Ditto (an iPhone app) lets you tell those same people and businesses where you’ll be.
Think about what that lets you do that Foursquare doesn’t. I’ll be at USVP later today. You can meet me there. But if I only check in where I’ll am, it’s too late for you to change your plans and come and meet me.
Or, think about a business. Is the best time to try to send me an offer the one after I’ve sat down for lunch at a business? Or, when I tell you at 9 a.m. that I’ll be in downtown Palo Alto for lunch? Wouldn’t a business be far more likely to want to talk to me if it new it could win my business? Sure!
Definitely one of the apps that will be on my list of things to try at SXSW.
