I find a lot of people dealing with startups ... employees and founders (mostly) posting practically everything on social media from going to an event, launching a product / service, last night's dinner, a picture of every coffee in the day, a message in the loo and a coworker dozing off ... etc I always wonder if this is a means of guerrilla marketing, being social, expressing camaraderie or showing gratitude? I think of it as social validation and wonder its impact on creativity, morale, etc (if any at all)
