What is freemium and what is the freemium economy all about? Freemium is a term combining "free" and "premium," and is a business model based on the idea of charging absolutely nothing for a basic product or service. Perhaps one of the better known Freemium products is Yammer, an enterprise social network. Clearly the model works because more and more companies are using it, and not just for Beta versions of their products or service. However, users need to be aware that they have few rights if the Freemium prodct/service is removed - along with all of their carefully curated content. Best to remember the mantra "if it's a free service, you are the product"!
