I think it's a good idea. While Wikipedia does a great job at this, we can't close a question as a duplicate of a Wikipedia article.

These questions do tend to [get out of hand](http://serverfault.com/questions/231161/what-is-this-very-short-power-cable-called).

There is _no_ good reason for someone to get 100 upvotes for saying "it's a short extension cord." There's also no good reason for you to net 90 rep for recognizing a display port cable. :P I think a CW for these silly rep magnets would take care of the problem nicely.
