Talk Business contributor Emily Reeves shares thoughts on the maturing of social media sites, such as Facebook, LinkedIn, Groupon and Twitter.

These sites haven’t been around for generations, but in their relatively brief existence, they’ve become integral parts of our daily lives on a personal and business level.

Most interestingly, these sites (and others) have found a diversified way to make money. And in recent months, we’ve seen widespread speculation and proof that some sites will succeed as publicly traded companies.

Reeves, director of account management and research at Stone Ward Communications, said that this round of "web sites gone public" has some marked differences from a decade ago when the dot-com bubble burst.

"At this point, they’re established. They’ve been able to prove to potential investors that they can make money, there is actual earnings potential," she said in a recent appearance on Talk Business. "These companies have huge user bases now and that’s a very desirable target of people that marketers want to reach."
