'Tis the first pre-season appearance of Santa, and he's gone corporate in an ad for ePresence. The ad from the Garfield Group, Trenton, N.J., asks, "Just how does he know who's been naughty or nice?" and advises, "Since you can't use elves, let us suggest ePresence" to help provide customers with a personalized e-business experience.
