One social platform that I have been meaning to write a “By the Numbers” stat post about for a while, but haven’t had the time, is Tumblr.  With the major news about Yahoo’s purchase of Tumblr for $1.1 billion, I guess now is as good a time as any to explore just what Marissa and company are purchasing.
