re: Zuckerberg Photo Flap: 4 Lessons
The biggest lesson that anyone needs to know about social media is that, most likely than not, you're creating content and attracting users (friends, clients, etc.) for someone else's Internet advertising platform. Any time an ad gets served on a web page, someone's getting paid for it - and when you create content (i.e. your status updates) and people log in to read them, they see the ads (or at least the call is made to the server to deliver the ad - whether or not it gets rendered in the browser is a different story), someone makes money. Getting attention/spotlight brings revenue... for someone. The Zuckerbergs make money because they run the platform - how are you making money from their platform?
At any rate, the issues that you're seeing here come from those who are creating things for the general public (i.e. lowest common denominator) and putting them out there without appropriate education regarding the ramifications of their actions. Then the general public is finding out, sometimes the hard way, how to navigate around. "Digital Etiquette" is something you'll find dancing in the meadow with unicorns, lepreichans and the Easter Bunny. Some would even say that etiquette in general is dying a slow, painful death - thanks to the digital age.
