Detailed, real-time information is good for stock trading, but not so great for other purposes, according to an online campaign for Ameritrade from OgilvyInteractive/New York. In one superstitial, we see a wedding scene that is soon cluttered with useless information, like the groom's body temperature and the "bride's distance from Venus." As the copy says, this sort of informational overload is a bad idea for weddings but a "good idea for online trading." Other executions drive home the same point for Ameritrade's "5-second guarantee," which doesn't work so well for sightseeing or haircuts.
