Going around the web for web sites to test I came along the ever useful blog of Nikhilk Kothari, author of wonders such as Script# or Facebook.NET. I knew Nikhilk was fond of things like CSS or Silverlight, so we reckoned the page was pristine in terms of markup.

See for yourself what I found when downloading his home page and putting it through a dose of Aggiorno:

I then showed the video to Nikhilk, who found it really funny and told us that it's been quite a while since he last looked at the base source code (2003 he said!).

Similar to Nikhilk's, there are tons of pages that were coded awhile and never looked back at.

Does your markup validate? If not, you could be missing public by not being accessible and sucking at SEO!

As shown in the video, with Aggiorno you can take that legacy code and, after a couple of clicks, get on the bandwagon of web standards. 

Remember that Aggiorno works on XHTML, ASP.NET and PHP source code, so no excuses from you, sir: come download Aggiorno and give it a try!
