Professional Article Review

The article is titled, "They loved your GPA, then they saw your Tweets".  The article is about how some colleges look at student social media accounts to find out more about them.  In this article, it tells that some high school seniors are turned away from some colleges because of what they have posted on social media.  The article was not very surprising, and I understood all of it.  This article makes me think, if you have something you want to hide from people, why are you posting it on social media?  This article just makes me want to stay away from social media for a lot longer, as I don't use it anyway.
