A lofty online debate hosted by The Economist magazine reached a sobering conclusion for anyone who sees social media as the next big boost—for meetings or for the economy as a whole.

After weighing the arguments, readers concluded that social media companies like Facebook, LinkedIn, and Groupon are the leading edge of a new technology bubble. With the dot.com bust still a painful memory, it’s worth asking whether there are risks in a collection of social media platforms that are rapidly becoming a cornerstone of our industry.

In the debate, retired “serial entrepreneur” Steve Blank compared the sky-high valuation of social media stocks to the rise and fall of the dot.com and housing markets. With Facebook and LinkedIn valued in the billions, Blank said the bubble is on, with too many investors assuming every stock will be a winner.

“Obviously, some of these companies will have hundreds of millions of customers, unprecedented revenue growth, and great profits,” he wrote. But when some or many of them crash, anyone who depends on them will be collateral damage.

Venture capital king Ben Horowitz, who apparently engineered Skype’s $8.5 billion sale to Microsoft, countered that e-commerce is soaring to new levels. “With costs 100 times lower, programmer productivity 10 times higher, and the market 50 times larger, it stands to reason that many more Internet businesses will work today than the last time around.” And with billions of mobile customers trading up to full-feature smartphones, the Internet is poised to double in size.

Moreover, “software is eating the world,” transforming or obliterating industries like print publishing, music distribution, radio, and direct marketing. With so much new business right around the corner, he argued that the high stock prices attached to social media “have not become completely divorced from any rational thought.”

There are some frontline truths we should keep in mind before we take too much comfort from Horowitz’s remarks:

• Even if the Internet doubles in size, our audiences’ capacity for new information will not. Online clutter may become an overwhelming problem for meeting messaging whether or not the tech bubble collapses.
• The proliferation of social media platforms may be our best evidence of an overheated market. The antidote for meeting organizations is to get clear about what they expect from social media and which platforms can deliver it, then ignore the rest of the hype.
• If or when the bubble eventually bursts, the fall could come very quickly. So meetings should maintain multiple channels for contacting attendees and keeping conference communities connected.

And finally, “software eating the world” is not a good thing when your own organization is on the dinner menu. Our industry is making a case for the value of meetings, but we don’t always win the argument. If your social media provider believes that face-to-face belongs to the last century, you might want to watch your back.
