Dr. Williams' Patented Wiki-Hoover

From time to time, the noble reader may happen upon a mention of a "Wiki Hoover" in the list of recent changes. Be not alarmed; this is merely an automatic Device, developed by our noble Friend Dr. I. Williams, which is wheeled out in the Guide offices upon occasion to apply a dose of hooving to the Guide in such places that require it. Your experience should not be adversely affected; indeed, it will actually be smoother in certain ways. The curious should apply to Dr. Williams for a handbill on his Invention; he may also usually be found at meetings of the Perl-mongers, where questions can be put to him.
