If you choose not to post pics of yourself, your food and inspirational quotes on the internet, you're a weirdo?
Not at all.
But for some reason, the people that do are indeed weirdos.
I know a lot of women in their 20s and 30s at all different stages of life: fast-food/Wal-Mart workers, PhD candidates, doctors, strippers, lawyers, engineers, single mothers, happily married, pilots, weatherpeople, rappers, politicians, etc.
And the only ones in the 20s age range who don't have IG (and Twitter I suppose should be included) are weird or hyercons. women.
This is a sample size of about 50 at least.
