What links here

What links here or WLH is a standard link in MediaWiki and some other wiki code. Off to the left in the Develop Wiki for instance you can see "| what links here" - click on that, and you will see what links to this page you are reading right now.

MediaWiki carefully differentiates reference to redirects but lumps all those usages with variant anchor text together. Thus, disciplined use of redirects can make what links here much more useful to quickly figure out the conceptual organization of a large public wiki. However, overuse of the "pipe trick" obscures the actual nature of these references and makes the overall function of any page very difficult to quickly determine.

How should Consumerium Services exploit these facilities to improve the Publish Wiki's usefulness? What role does WLH play in Consumerium buying signal and point of purchase activity?
