"If I had the cash to invest, I would certainly buy this stock," said Tracey Werner, principal of Blabbermouth Communications, a social media marketing and public relations firm in Easton.

Tom Young of Social Media on Fire in Catasauqua said he's a little less enthusiastic about the IPO.

"I'm mixed about it. Facebook CEO Mark Zuckerberg didn't even show up for the IPO meeting. I'm not going to buy the stock," he said.

The big question for both is whether or not the website is a good long-term investment.

"Is social media as a whole just a flash in the pan?" asked Werner. "I think it's already had a pretty long longevity. It's probably got several years left in it."

But Young asked if it will be able to build revenue.

Just days before the IPO, General Motors announced it would be yanking its ads from Facebook, calling it an ineffective venue to sell cars. But the Ford Motor Co. then stepped in and defended the site as a strong part of its marketing efforts.

"When I wanted to buy a car I went to Cars.com. I didn't go to Facebook," said Young. However he added that he did later "friend" the dealership he purchased his car from on the Facebook site.

"I myself advertise on Facebook," said Young. He said he has also set up Facebook ads for clients such as Pioneer Glass in Emmaus.

"I noticed for local, I get more reaction from it," he said. "But as for national ads, I don't even look at a whole lot of those unless something catches my eye."

Other Lehigh Valley area businesses have used paid ads on Facebook, including Shula's Steakhouse in the Promenade Shops at Saucon Valley and Century 21 Keim Real Estate in Allentown.

"We used to do paid ads, but I don't know if we got any sales out of it," said Realtor Loren Keim.

But Werner said the same could be said about any marketing plan.

"Marketing isn't 100 percent – I get an ad and I get customers. I do Facebook ads for awareness," she said.

For that reason alone she said she thinks Facebook has value for investors, even if it is just a trend.

"Just because it is a trend doesn't mean you shouldn't get involved."
