(FORTUNE Magazine) – Expect 1994 to be a year of pragmatism. Coffee is back, clear colas out, and hemlines are where you want them to be. Says Barbara Feigin, an executive VP at Grey Advertising: ''Consumers have seized the catbird seat; they're tired of being passive receivers.'' This trend is very evident in entertainment. More are tuning in to shock jocks like Howard Stern and Rush Limbaugh, who speak their minds freely, unbeholden to programming execs, sponsors, pressure groups, or taste. On the subject of bigmouths: The passage of NAFTA seems to have left Ross Perot in diminished form; his sound bites have sure lost a few teeth. But if Perotspeak is waning, so-called ''uptalk,'' a likely relative of Valley Girl patois (linguists aren't sure), is catching on with teenagers. It's a new style of speaking? The kids' declarative statements sound like questions? It can be really annoying?
