W3C Standards Compliant

I was checking various websites using this W3C validator:

http://validator.w3.org

and just wanted to congratulate the ruby home site as passing:

www.ruby-lang.org

In comparison, those slackers over at www.python.org show 1 error and
1 warning on their site. :-)

Here are some other sites that pass 100%:

www.msn.com
www.firefox.com
www.mozilla.com
www.oasis-open.org

It's nice to see prominent OSS projects taking standards seriously.
But hey, what's with those Microshaft people?

And a shocker, www.openoffice.org has 4 ERRORS! (as of July 7, 2009)

Also, some prominent sites that have errors:

www.gmail.com
yahoo.com" target="_blank">www.yahoo.com
www.google.com

I did this just for fun.

But maybe it would be a nice see Merb, Ramaze, Sinatra or.... used to
write a
little web app to track and list W3C (non)conformance of sites (if
such a project doesn't already exist), Let's out the bad and hail the
good!

Peace
