Too true! I recently made a post myself about my blog ranking at a Genius Level reading ability. I pondered whether or not it was a good thing, since the Melissa Donovan's post (where I first saw the quiz) was proposing that it was good to rank lower so more people could understand you.
The thing is, when you dumb stuff down, you know what you get?
But that's not how I write. It's not the type of people who appreciate my writing. So why should I "dumb down" what I write in order to reach the average middleman? That was my stance, and I don't mind saying that I feel justified that a major blogger like Seth sees things my way.
One of the comments on my previous blog noted that you should write the way you speak when blogging. That opens up the conversation. I completely agree with that, and the thing is... I do speak this way. Which is why I write this way. I need not apologize for my love of grammar and syntax!
