Thanks for your input, Ratazong
. I do agree with you that repeated lengthy use of links to a particular site gives more of a reason to have the shortcut.
However, I was unaware that a show stopper criterion to introduce a shortcut was that there aren't already many existing links. Were there a lot of links to the Urban Dictionary when [ud://]
was introduced? In fact, Wolfram|Alpha is pretty new (launched in May 2009) so there may not be as many links.
Also, it's the lack of using Wolfram|Alpha that we can encourage by introducing this shortcut. Many posts have convoluted explanations that could have otherwise been described more clearly with Wolfram|Alpha, IMHO.
