You can turn your back on the social networks that matter in your field and be free and independent running your own site on your own domain. But increasingly that freedom is just the freedom to be ignored, the freedom to starve. We need to use social networks to get heard and this forces us into digital serfdom. We give more power to Big Web companies with every tweet and page we post to their networks while hoping to get a bit of traffic and attention back for ourselves. The open web of free and independent websites has never looked so weak.
Facebook’s Open Graph technology allows third-party websites to tell Facebook what people are doing. It extends Facebook’s Like button to include any action that the site owners think might be interesting to Facebook. Play a song and your music streaming site tells Facebook what you’ve played. Read a newspaper article and Facebook knows what you’ve read. LOL at a lolcat and your LOL gets logged for all time on your indelible activity record. Facebook calls this “frictionless sharing”, which is their euphemism for silent total surveillance. Once you’ve signed up for this (and it is optional, at least for now) you don’t need to do anything else to “share” your activity with Facebook. It’s completely automatic.
