Mary Gallagher recently received an e-mail from the Metropolitan Tucson Convention & Visitors Bureau offering "hot deals." But there was a catch: In order to receive them, she had to follow Tucson's tourist authority on Twitter and friend it on Facebook.

That didn't sit well with Gallagher, a travel writer, who said she receives enough deals each day.

"How much Facebook and Twitter drivel could you spend each day reading?" she said. "This really, really annoys me."

Are travelers overloaded by social media? It's a timely question, given the release of "The Social Network," which topped the box office for several weeks in October, and is about the origin of Facebook, the most successful social network on the planet.

Travel is a huge component of social networking, propelling applications like Where I've Been -- a website that allows users to mark their travel history on a color-coded map -- to stardom.

"It can get to the point where it's too much," said Brian Ek, who oversees some of Priceline's social media efforts. Which is to say, somewhere along the line, the travel experience isn't meaningfully enhanced by having more friends or followers.

"I'm not sure if, as a traveler, you have to participate in a social network in order to have a good trip," he said.

But where's the line? Gallagher saw it when Tucson e-mailed her. She replied to the sender, complaining that social networking deals exclude travelers who don't participate in these newer networks. She also asked that her name be deleted from Tucson's distribution list.

A 2010 YPartnership survey suggests most travelers are probably still looking for the line. Results show that 91 percent of respondents use Facebook, about a quarter use MySpace, and 17 percent are on Twitter. But the research also notes that only 1 in 20 leisure travelers has ever made a travel decision based primarily on research or feedback received from a social networking site.

A recent University of Maryland study found that American college students are addicted to social media. In fact, being away from social media was like a withdrawal, similar to the kind experienced by an alcoholic. One of the researchers, Susan Moeller, described some of the subjects as "incredibly addicted."

A recent survey of frequent travelers by Egnyte, an information technology company, found that 53 percent of people admit to using their smart phone when in a hotel bathroom.

When the line between reality and virtual reality start to blur, you could be in trouble. "You lose track with whether or not you've spoken with someone or whether you've seen something on Twitter or Facebook," said Chris McGinnis, a travel blogger with an active social network. McGinnis said older travelers, who can remember a time before social networking, might find something wrong with this behavior when it's pointed out to them. But younger travelers think nothing of it. And that worries him.

And who said you can never have too many friends? Many travel companies, including media-savvy JetBlue, have initiatives aimed at boosting networks simply for the sake of having the highest profile. JetBlue (1.5 million Twitter followers) recently gave away 25,000 frequent flier miles to random followers.

On the flip side, there are individual travelers who are in the business of collecting friends and followers, too. Experts would diagnose this kind of compulsive behavior as an addiction if it involved anything else.

If you're obsessively collecting new followers, can't bear to be apart from your cell phone and often confuse what's happening on your social network with reality, you, like Gallagher, have found the line.
