Kickstarter: unsurprisingly, this crowdfunding resource is being used toward funding folkie projects as well such as Doug Plummer's 2014 Contra Dance Calendar.
Dance Video Archive: This site, which seems to be run by Bob Green, crowdsources videos of CDSS member organizations' dances.
Various entries to Wikis (such as this one on Wikia) and crowdsourced attempts to identify dancers/band members in photos help to chronicle the ongoing contra dance movement and keep the community aspect of this even in the digital age. I find it very interesting that while the times have changed, the values and community norms do not seem to have changed very much at all.
