Sounds scary and important but what does it actually mean to you and your website and why is validation important?
Firstly let us give you an excerpt from WC3 as they are the validation setters for the internet world:"Validation is a process of checking your documents against a formal Standard, such as those published by the World Wide Web Consortium (W3C) for HTML and XML-derived Web document types.
Validation is the process of checking if the language structure is correct.

I’ve took a look at the reasons behind validation and checked out 25 of the web’s most popular websites to see if they bother validating their code.
Well, each browser is different and not having proper code could affect the way people view the page.
Also, if you are a web designer, it is unprofessional to have a website for a client that does not validate.
As a very basic example, a validated website will not allow an image without an ALT attribute and ALT attributes are important for use with screen readers (which a user with a visionary impairment may use to 'read out' a website to them).
A validated website does not instantly mean your website is 100% accessible but it is a very good place to start and build upon.
Use the W3C Validator to check your site then submit your link and comments below.
It would also be good to hear your points about validation and if you think it's worthwhile.
Ampersands must be written ‘&’ and not just ‘&’. I think it's worthwhile validating your websites and it's good practice.
