What's the Readability of this Blog?

I just learned about this reading level test from Randy's post. So, here are my results:

Total sentences - 4330
Total words - 17855
Average words per Sentence - 4.12
Words with 1 Syllable - 8835
Words with 2 Syllables - 3758
Words with 3 Syllables - 2159
Words with 4 or more Syllables - 3103
Percentage of word with three or more syllables - 29.47%
Average Syllables per Word - 1.97
Gunning Fog Index - 13.44
Flesch Reading Ease - 35.68
Flesch-Kincaid Grade - 9.31

Hm ... . According to this test, a person reading this blog would have to a high school, or maybe a little bit of a college education in order to read it. Does this sound right? I didn't expect it to be that high. What do you think?
