I was checking W3C Markup Validation and in report it was shown that that pages (not post or any other URL's just PAGES) at investmentcontrarians.com are 301 redirected.
e.g. original URL "http://www.investmentcontrarians.com/debt-crisis" which is redirected to "http://www.investmentcontrarians.com/debt-crisis/"
I know that its not that serious issue, but still want to know why only pages are being redirected and how can we avoid it.
