Are you +1 on Google?
Is your face on Facebook?
Do you tweet on Twitter?
Are you LinkedIn?

Even a business entity needs to develop its social skills

It’s never been easier to close the gap between your and your target market. Make a fan page for your business on Facebook, start tweeting some micro-blogs on Twitter, and broaden your business connections with LinkedIn. Exposure can spread like wildfire on Facebook, it’s very easy to keep up with your Twitter once you’ve begun, and the connections will come looking for you on LinkedIn. See what develops when you reach out to your target market in a way that’s personal to them! Facebook, Twitter, and LinkedIn are just a few of the wrecking balls breaking the communication barriers that stood between CEO and Average Joe, so give new ears to what your target market is saying, and share your company’s personality!

BUT! If you don't have a plan you will not succeed. Just because someone can post someting on Facebook doesn't make them a marketing expert.
