Ok I thought it was a load of crap as well but it has worked for me.
When I tried to validate my sites with this about 6 weeks ago, none of my sites passed as they were full of my crap coding. A bit of work and now they ALL pass.
What does it mean? Clean code my friends and G loves clean code.
My main site is now number 1 on G for a finance keyword that has 40k searches a month and 27m competing websites. Not only that but I have finally achieved authority status with it and whilst you may say that the W3C had nothing to do with it, I say it has and all of my sites have jumped up G in the last 6 weeks.
If you can, do it. Here is the link
