Should read: The most common english words in rss feeds. I would imagine that it is not necessarily representative of the entire language. Specifically I doubt 'government' is the second most used word over 10 letters (although I obviously have no evidence :) ).
It's surprising to me that this is getting voted up because data on common English words is easily available on the web and well known to anyone who's done basic crypto. stuff.
When I was looking for a list like the one I built I did run across this one. Unfortunately, I needed far more than 1000 words and I also wanted to have information on occurrence counts. If you have additional resources I'd love to see them - perhaps I could add links to similar lists to the post.
