User blog comment:Eladkse/An Idea: URL Shortening/@comment-26686429-20110609132210

Firstly, there's no TLD .ia - so wik.ia wouldn't work (and even if there was, it probably would've already been snapped up by someone). However - there may be merit to the feature itself. In this case, I don't agree, though - if you want to shorten a URL, you can use bit.ly or tinyurl, so I don't see what extra utility you'd get of having an in-house Wikia URL shortener.
 * If a Wiki's pagename is long, you might want to consider a redirect from something shorter - this has the added advantage of people searching that page and getting what they want already.
 * Tl;dr: I wouldn't use this feature, and I don't see any advantage of it as opposed to the aforementioned bit.ly or tinyurl, etc - in addition, anyone can create a redirect of a long pagename on Wikia.
