One of my favorite stat tools for Twitter is Twitter Grader.

Why?

Well, it’s not really because of the grade they give, for even they state.

“What Twitter Grader is trying to measure is the power, reach and authority of a twitter account. In other words, when you tweet, what kind of an impact does it have?”

This, of course, is all subjective.

Which means putting your focus on the actual grade would be a wrong approach...
