Wow so much enthusiasm.
Small correction: personally, i dont see edgeryders working for charity, rather the projects around here are looking to make a positive contribution and many times they need to remain independent and non-profit to retain credibility among those whom they wish to serve. For example new kinds of sharing economy platforms which aim to redistribute value to contributors rather than make profits through large margins - @damiano described it here. Another thing is the dependency on public funding which also tends to compromise a project’s life because it is short termed and not long term outcome oriented.
In october at our upcoming festival in Brussels (19-21) there is a session dedicated to sustainability called The Edge of Funding - I’m curious to see what you think - it departs from the constraints people have to access resources.
