Candidates' Crowdsourcing Apps

"Crowdsourcing" is often applied gathering information from online communities, but it is also a way of putting those communities to work. Presidential candidates are using crowdsourcing applications that put volunteers to work in their own homes calling potential voters around the country. Clinton's "Call Center" landing page shows a typical app's workflow step-by-step.  Obama's landing page for a similar app has a different engagement style.

Both websites get you to these landing pages with a single click from a home page call-to-action. At the time of this post, McCain's home page did not appear to have a similar call and a buried exhortation to "Make Phone Calls" seems to have a broken link.
