Has Your Website Been ... De-deprecated??

I found out that deprecated HTML on your website could hurt your websites ranking & functionality. See: http://webdesign.about.com/od/htmltags/a/bltags_deprctag.htm I was really surprised at some of the tags that are deprecated, some of which once seemed very critical and advanced, but are now hinging on the obsolete. Turns out CSS (style sheets) are now even more critical to web site design. This identifies deprecated HTML tags: http://www.codehelp.co.uk/html/deprecated.html
