What site has the highest percentage of "Advanced" pages?
I thought uclue.com was quite high at 9%, but wikipedia.org is way above that at 31% and (surprising to me) britannica.com is at 37%.
Foxnews.com is 2%, by comparison. |
stanford.edu -> 64% advanced
harvard.edu -> 84% advanced |
An advanced reading level is very different than an advanced concept. Reading levels are often rated by age or education level. More readable documents score a lower age as their reading level. Some documents may have an advanced reading level because they are very poorly written. Wikipedia should not strive for an advanced reading level.

I wonder if they used this as their reference point.
[site:guttenberg.org] 100% intermediate
http://www.google.com/search?q=site%3Aguttenberg.org&tbs=rl%3A1
|
I found some other sites that are 100% intermediate. I suspect that Google has not yet graded their reading levels. |
I'm surprised this wasn't introduced into labs instead of going live. |
Compare the first two.
[est] lr=lang_fr basic 33% intermediate 33% advanced 33%
