I like the idea behind responding to national emergencies with simple and quickly implemented tools that call for people to do something. I also like the idea behind sites like Kickstarter that propose a solution to a problem and ask for public support. I think artists can really do something with social impact. And I think LinkedIn can really give them a medium for gathering support for social impact concept art. I'm not too sure how that might look, but there is a need that I think LinkedIn can provide a solution for.
