Well, not bad for me, I got a Solid "D"! My problem was that I spent so much time on sourcing my chart (and yes, I compiled ALL that info by myself, just me and my little laptop, and in-app Calculator!) Having said that, I think the score is accurate and fair. Looking back, I realize I spent so much time on the information that I shorted the "presentation" and it really detracted from the overall message. I kinda made up for it in some of the comments, but that info could have just as easily been presented in the main body of the article.
I see @toiletscrubbers being an effective tool for serious content producers, in the minimum becoming a "How NOT To" guide...
