This isn't definitive, but search economist.com using Google for the following:<p>Keynes - 1640 results<p>Adam Smith || John Stuart Mill (classical economics) - 992<p>Hayek || Milton Friedman (Chicago school economics) - 858<p>Mises (Austrian economics) - 431<p>Of course it's better to read it and form an opinion from the actual content for yourself but I think these results are fairly indicative.
