How did posting online change from, "Be careful what you put online!" to many sharing a lot under real names?
I know at this point a lot of it is related to money, but there was a transitional time that led to this point that I'm still confused by.
What details changed about online spaces that made many folks more comfortable sharing so much under their real names between the "Be careful!" times to where we are now?
I'm not sure what you're referring to, but for what it's worth, when I got online in the 90s, I shared as little as possible (it was under my email on Usenet, mostly). Since then, I've used different aliases on each and every service, often different emails as well and have never shared anything personal. The very idea seems ludicrous to me.
I know a lot of people do it. I honestly have absolutely no idea why.
But then I never could understand why people took selfies either, so maybe it's just me.
