Defining Light, Medium, & Heavy Social Media users: Survey

I was hoping to get a bit of help from some of my readers and followers in defining social media use by the number of updates a user posts to their social media profiles. The results of this brief poll will actually inform a similar type of question on a survey I have developed for my dissertation, so your help is much appreciated. Also if you disagree with my scales of Light, Medium, and Heavy, then please leave a comment explaining what might be a more appropriate way to determine someones social media use in a given day.   Thanks!
