It has come to my attention that some illiterate non-people write and even say "an homage". For instance, in this wikipedia article (which I have since corrected, so that's a link to an older version). No doubt this error was made by analogy with the somewhat more widely used "an hotel", which is also an error. Neither the OED nor Fowler support this hatefulness in modern writing.
Therefore, when I become benevolent dictator of the world, anyone committing these linguistic sins will be shot.
