Seth Godin blogs:
Society changes when we change what we're embarrassed about. In just fifty years, we've made it shameful to be publicly racist. In just ten years, someone who professes to not know how to use the internet is seen as a fool. The question, then, is how long before we will be ashamed at being uninformed, at spouting pseudoscience, at believing thin propaganda?
My knee-jerk reaction is: we seem to be moving in the opposite direction on this one: social media encourages people to share superficial observations and half-baked ideas with others.
Considering that, anyone with a blog does this. Myself included. Seth Godin included.
