[Show HN] CrowdPiper - experiments using popular social networks

How can we use so many popular social networks existing right now in interesting, creative, & meaningful ways? With CrowdPiper (http://crowdpiper.tumblr.com) I'm trying to find out exactly that. Crowd Piper lets you rally a crowd to participate in creative experiments on your favorite social networks. For example, you can explore fun ways of using photos on Pinterest or viral methods for marketing on Twitter and so on.

The experiments, however, MUST involve lots of people & all contents MUST be crowd-sourced!

I have submitted few of my own experiments & included a couple more from friends & other links. Feel free to submit your own new experiments or participate in one of them.
