Foursquare has more than a half million users, 1.4 million venues and more than 15.5 MILLION check-ins.... And has only been around for 1 year! Although the trend hasn't gone mainstream yet, I think it will relatively soon. There are many pros and cons to Foursquare, and it's value hasn't been defined quite yet, but I see many pluses to this start-up.
First of all, many people refuse to use Foursquare because it's deemed "unsafe" to be telling everyone where you are and what you're doing at all times. But twitter and facebook both can find your locations and tweet where you are, while Facebook status updates let people know where you are, who you're with and what you're doing... It's basically the same thing. I think people need to get past this part of it, and see Foursquare and even Gowalla for what they're worth...
Businesses and venues need to start embracing these as well, because once they start offering more discounts and deals for all customers checking in (and special deals to "Mayors", Starbucks) people will be more inclined to check it out and see what good it could do for them. Businesses really need to look into it because it could open so many doors, create brand and product loyalty to their food, products, whatever AND create an entirely new channel to interact with customers. How great would it be to walk into your favorite coffee place, where everyone knows who you are and congratulates you on being the "mayor"... Stupid, maybe... but fun enough for all, and who doesn't want to compete with others to be a mayor when all you have to do is frequent the shop?
I think it will be interesting to see how well these do in the next year and see how they transform. Look out for all of this.
