As more and more people are stockpiling online friends and contacts through social networks, it makes sense to let them be as giving to their online friends as to their offline buddies. Online flower store Social Flowers spotted a business opportunity and has created a way for consumers to send flowers to their Facebook friends without having to ask for their personal details. How it works? Users install the Social Flowers Facebook application, select a recipient from their friends list, pick a floral gift and pay. Social Flowers then sends the recipient an email and a Facebook notification requesting their address and the flowers are delivered by one of 30,000 local florists in the US and Canada.
