As with a large number of these additions that stop being developed on Wikia: Rinse and repeat. That will never change :P
 * 1) Someone at Wikia comes up with the idea (usually someone who, by now, doesn't even work with Wikia any more)
 * 2) The engineers develop the script for use on Wikia
 * 3) Some product managers or community support users prod large wiki's into using them to "display it" in a live environment
 * 4) The idea is released to all wiki's without warning and people are encouraged to use it
 * 5) Release day bugs are fixed, as are any "system breaking" bugs with the feature
 * 6) The idea is abandoned within 4 weeks and development stops.
 * 7) After a few years, the idea is retired from Wikia and disappears, essentially wasting everyone's time.
