One caveat: If a lot of recruiting coordinators are following players on Twitter, it's not just for videos, and my not be for things like that at all.
Sometimes they're looking for the opportunity to schmooze a kid they like and keep him in the fold.
Other times, they're lurking, just watching what the kid posts to see if he's mature, etc.
So if you're a player prone to racist posts, posts about weed or alcohol or such, or carping about your playing time, your HS coach or your teammates, the fact that RC's might follow your Twitter feed should lead you to take care what you put out there for everyone to see and learn about you.
But the way it typically works is, kids are careless, kids are undisciplined, and kids don't listen to warnings given by adults about such things. And so, many of them hang themselves without having a clue that they're doing it.
