Oprah gives Skype the Twitter treatment today: Will it help or hurt?

Oprah Winfrey, who has already been using Skype to interview guests who can't make it to her studio, is focusing her entire show today on Skype's phone service.

"Where the Skype Are You?" is the title of today's program. She'll speak to guests from various locations, including the North Pole, inside a submarine and aboard a flying plane, according to the Wall Street Journal.

This uber (even for Oprah) Skype-hype begs the question: Does her blessing of Skype help it become a household product or does it ignite a backlash that its fans will equate with the service jumping the shark?
