There’s an e-commerce revolution coming that will further blur the boundaries that have traditionally existed between buyers and sellers. That’s not necessarily a bad thing, but it may take some getting used to in terms of its potential impact on the relationships people have with one another on social networks.
With Lemonade Stand, users can search for things to buy in a location-based manner, or add their own listings of things they wish to sell. The application is currently available as a client for Android, with a possible Windows Phone 7 version on the way soon as well, from a 3rd party developer that released an early version. Its Lemonade Stand API allows other developers to either code their own clients or use it in mashups.
