Not Practising What You Preach?

I have blogged about YSlow, a very nice tool from Yahoo, that gives performance indicators of your web page. Guess what? I ran it on their own page (http://developer.yahoo.com/yslow/) and found that they got 3 F’s, 1 C and 1 B. Overall score was a D (62/100). A case of not practising what you preach?
