Have you ever tried to parse a non valid HTML document whith regular expressions to extract data ?
Missing end tags, incomplete tags, missing > and stuff like that make it a pain in the ass.
Do you think the google spider likes to run into buggy sites ?
It does not care about perfect validation but the validator helps alot to avoid most common bugs.
Non Valid CSS causes alot of display issues , so why not use valid CSS.
As webdesigners its our task to make pages that give good results on most browsers, and make it easy for searchengines to extract the data.
Hello, yes of course.
There are some important things to do on a site - but it all has its limitations.
For example: valid css may be a issue with some browsers, but I don't think that a spider will take this into account for the SERPs.
There are a lot of fancy stuff out there you'll never get through the css validator. So you'll need to take your own pros & cons into account.
Missing end tags, incomplete tags, missing > and stuff like that make it a pain in the ass.
As I said, this may be a real issue but it also depends on the purpose of your site.
But... I didn't say, that HTML validation is a stupid activity at all.
My statement was addressed the "CSS looks worse" part of the post.
- Just a few minor Problems whith validation nothing serious, you should fix em

- CSS looks worse
And again, it may be an issue but it doesn't harm your SERPs.
So if you ask me again: Nice pages!
Taking a robot (validator) to get some arguments for being critical is not part of my ambitions.
