Here is a link to the actual study. (I actually find this fascinating in comparison to your actual topic) Epic facial hair is timeless.

My one issue with the study is that they start by talking about how social media has changed the way we communicate, speak, type/write etc.
But then in the study they use an e-mail, an inquiry into the sale of a home (a significant purchase/transaction) in other words... business. Most people tend to view e-mail as pretty formal. There is plenty of literature available on effective e-mail writing, professional e-mail writing, the
importance of a well crafted e-mail, etc.
I think the study would have been far more effective/poignant if it either used both e-mail and a facebook post, or if it instead simply focused solely on the facebook post.
I know plenty of hardcore grammar nazis that look past "mistakes" in a text or twitter post, the point of those is that they are shorthand.
Oh and btw apple... I NEVER mean "ducking".
