Craig Newmark tells the 140Conf crowd in New York to make your mark online by contributing and giving where and whenever you can. Below is a video of his talk.
Says Craig, “Press should be the immune system of democracy.” By contrast to a solo video, here is a Webdoc created during his talk which incorporates photos, tweets and a simple survey, all of which only took a few minutes to create and a couple of button clicks to embed this here, as easy as embedding a YouTube video via HTML code. The same video could have been included in the webdoc as well for added richness and diversity.
Disclosure: I provide some consulting to the Webdoc team.
