Sounds about right
There’s a site out there that is supposed to answer the question “what’s your blog’s reading level?” When you download the resulting badge (right) it attempts to put a spammy link on your page. Because of this I’ve removed all links to the site, but you can find it by searching.
For what it’s worth (nothing), my other blogs, right reading, frisco vista, and buried mirror score “high school,” while seven junipers has graduated to “college (undergrad).”
I see a lot of sites boasting of scoring “genius,” but to get that score you would have to be doing something very wrong.
