Via Crof, here’s a readability analysis tool that assesses your website at the touch of a button. Here are the results for this site. Apparently I’m averaging 16.5 words per sentence, and am running at a shameful 32% passive setences. Improvements, I was thinking, will have to be made.
Unfortunately, their explanations of what all those numbers mean are pretty obtuse: “The Coleman-Liau Formula usually gives a lower grade than Kincaid, ARI and Flesch when applied to technical documents.”

My results are very similar to yours, but I have a lot less content on my main page for the algorithm to go through. Interesting site, but it is ambiguous in detailing what the scores mean.

LOL.
Do note that the calculator doesn’t know how to deal with bulleted lists. It’s telling me I have 75 words in some sentences. It’s probably doing the same with your link round-ups.
Both Crawford and I linked to readability.info earlier this year, with analysis of additional sites, though it’s a link worth repeating.
The link I really need is to MemoryRefresher.com…plus some tips on how to remember it! Thanks for the reminder, Derek.
Here’s what I got when I submitted my blog:

Meh, automatic tools for readability and grammar are watering down the artistic merits of writing.
Just my $0.02.
Yikes. After reviewing the readability of my site, I now see that I need to put more effort into improving my grammar!
I, too, had passive sentences in the 34% range.
I don’t think automatic tools are to blame. When I was in journalism school 13 years ago, I had to learn how to calculate the Fog index by hand. I got my hands on an automated tool the next year and have forever been thankful for the extra time I now have!
I submitted some writing and my passive writing score was 53% – whatever that means. I tried finding a few places to help explain it all but my google-fu evaded me. So I can’t tell you if my writing skills suck or not. *sigh* But i did find it interesting all of the various ways to analyze it. thx for the links
