A few months ago I was explaining some social media stuff to my boyfriend as he was working on his business concept. We were trying to figure out the most efficient ways to strategically distribute content across various social platforms for a small operation. I started making lists of the social media platforms that I use the most and the ones that seemed to make the most sense for his business. The list morphed into a slightly chaotic, criss-crossed chart that showed which sites naturally ported to others. In other words, which sites had buttons for sharing content to other sites.
I showed it to a few people who thought it was interesting, so I decided to take it to the next level, which is what you see up top. Sure, you can take Instagram photos of cool chairs you find at Future Perfect and manually pop 'em onto Svpply, but there's no direct port. And there are convoluted hacks and services like IFTTT that override this stuff, but The Natural Connections visualization only highlights direct ports that each site provides you with.
This is by no means an exhaustive display of all social media platforms, so I figured I'd add a bit more sites, including Kinja! Look out for that in the weeks to come... For now, I found it kind of interesting that Tumblr and Facebook are the only platforms that only allow inbound content, and don't allow users to port any content created on their sites to other sites. This definitely shows the heavy weights in the social media world.
If I missed anything or got something wrong, let me know!
