Session 2 had interesting presentations that highlighted the problems and opportunities of earning income or generating revenue on the web. It's as much about the culture and vision as about fees or donations--charging fees on Freecycle.org?#*!? As commenters said, volume has value, and Yahoo! Groups is earning income from the ad banners that support the regional Freecycle groups that serve its 3.5 million members. Freecycle is also earning income from Google ads, but faces the challenge that many others face in the nonprofit sector who need to pay their bills but don't want to rely on grants.
