Through the end of 1Q13, from when I first began blogging on November 16, the month of March yielded an all-time high in unique visitors (~950) to the blog (according to Google Analytics). A Unique Visitor is a separate/individual/distinct visitor.
In that same period of time, the stock price has fallen about 13-20%.
The share price drop is, at times, both puzzling and understandable. I contend blog readership is one metric, among many, of PV-10/Provectus awareness. I can directly and immediately measure it. It has been steadily growing.
