On the topic of social media applications, there seem to be three types of people: the super users, the avoiders, and the people that say, “I know I need to, but which ones and why?” Most business people probably fall into the last group: the ocean of people who lie between the early-adopter ?-geeks and those mind-boggling creatures who only check their email once a week or so. Yes, there’s potential there for good things to happen…if you’re actively using the right applications.

The number of applications and communities is overwhelming. Many of the most popular ones, like MySpace and YouTube, aren’t going to be all that helpful for professional interaction. That’s not true for every industry, though, so it’s worth asking around and seeing what your communities are using. If your colleagues, contacts, and customers are all using some other method of connecting, by all means go participate there. The point of this is for you to be able to make useful, meaningful connections and interact.

LinkedIn is a simple, useful tool for any professional. This is the business networking equivalent of being listed in the phone book. It doesn’t require very much attention and can provide a great deal of benefit. Spending half an hour building your profile lets you put your CV out there, easily find your network of contacts, and be visible for the sort of notice you want to receive. If you want to do more, there are great community features. People can recommend you and your work. You can ask questions through LinkedIn Answers and get answers from people who actually know what they’re talking about. If you need to hire someone or are looking for a job, it’s an ideal place to put out feelers. You won’t get clobbered with email from LinkedIn
