Hi I see a wordpress.com blog and on the latest post there is a redirect for the external links via "http://go2.wordpress.com/" redirect. This redirect is obfuscated - on hovering the link it displays a "http://google.com/url?..." redirect instead.
What is this and why is it suddenly on this post and not others?
Also, I see the redirect type is a 302 - surely this is harmful in terms of SEO for the destination links?
