Thoughts on wpd.mx domain

Hi,

It has been brought to my notice that wpd.mx has been setup as a url 
shortener for webplatform.org urls. for e.g. wpd.mx/apis/canvas 301s to 
http://docs.webplatform.org/wiki/apis/canvas. 
<http://docs.webplatform.org/wiki/apis/canvas>
This url has been indexed by Google and I don't like the thought of 
different urls pointing to the same content when a user is searching for 
canvas in a search engine. It dilutes the positive effects of a 
webplatform.org url.

Sorry to be a little picky but we should avoid all such short urls which 
confuse a user and in turn result in duplicate content being served to 
search engines. I see the benefit of a url shortener as it can be useful 
in social media campaigns as well as brand promotion for 
webplatform.org. I propose we use this url shortener on webplatform.org 
itself for e.g. webplatform.org/font-size which would redirect to 
docs.webplatform.org/css/properties/font-size. Every 301 is one 
additional request for a user which is not good in terms of performance. 
I would appreciate if we avoid 301s as far as possible unless it's 
absolutely required. Always, keep it simple :)

Any thoughts and feedback are much appreciated.
