I checked this a couple of years ago with the same results. The reading level of smays.com is elementary school, according to this website. The high end of the scale goes up college (maybe grad school?) and I think elementary school is the low end (do pre-schoolers read?).
I know it doesn’t sound like it, but I think it might be a good thing to write at a level that third graders can follow. I assure you, I’m not trying to write down to anyone. The words you read are the ones in hear in my head. Hmm. See smays blog. Blog smays, blog.
