Fully Valid, SEO-Friendly Social Media Links for WordPress
One of the things that will always get ya when validating is un-encoded characters in URLs. This is particularly epidemic in social bookmarking links where you are passing a bunch of information over to the service in the URL itself. Jeff Starr does one of his characteristically thorough posts on cleaning up your social media links. I really wish IntenseDebate would fix this problem. Since switching, my pages no longer validate soley because of the un-encoded URLs.
