With so many social networks and related communities, the choice is overwhelming. Why and maybe which type should you join?

There are two purposes to social networks,” says Jason Alba, author of “I’m On Facebook, Now What?” and “I’m on LinkedIn, Now What?”

• networking
• to enhance your brand

“LinkedIn has carved out a strong identification within the professional, job-seeking world,” says William Madway, professor of marketing at the Villanova School of Business. “It can offer more contacts and a professional, trustworthy environment for career-related networking. So, if I were attempting to advance myself professionally or career-wise, I’d be very inclined to turn first and foremost to LinkedIn.”

If LinkedIn just seems too suit-and-tie for you, Facebook is a good alternative and also on the list for many networking gurus.

Another site getting a lot of attention these days is Squidoo, a favorite for marketing expert Penny Sansevieri. She says it’s the best site for career enhancing because “you can upload a video of you, the page is very interactive, you can add widgets, a blog, just about anything.”

 There’s also some value in joining online networking groups that are focused on a particular geographic area, adds Mashable’s Ostrow. He recommends using Meetup.com to find out about groups in your area. Just put in your topic of interest and zip code, and you can find out about networking opportunities in your town.
