How Fastfrwrd Works
Fastfrwrd is to be seen as a purposeful Facebook alternative, with 300% renewable hosting (through GreenGeeks.com) where for each unit of dirty energy used to power the site, 3 units of green energy are bought so as to never have to use the dirty energy again eventually. The purpose of the site is to prevent Climate Change. Facebook has a timeline, groups, a marketplace, games, and gatherings. So does Fastfrwrd, but everything here is in the aim of making the planet greener, think of it as an entire environment to facilitate more and more people to work, play and live Carbon Neutrally.
A typical Fastfrwrd flow can look like this: Post on social; if you do something green, post for points; use points to buy stuff in games or on the marketplace; sign up to be a vendor and offer eco rewards to others from the marketplace as well; share information on group Docs to enable better eco action; host gatherings around eco topics and cowork with others to build your reputation and get reviews on your eco work; get better social and IRL (in real life) rewards from building your reputation. Each thing flows into the other.
