What drives people to tweet? Self promotion? Because it’s the thing to do? Because everyone else is? Bored? Unemployed? Day dreaming of self importance?

The smart ones are doing it for Search Engine Marketing (SEM). Let’s look at the numbers.

According to the “Consumer Internet Barometer” from TNS and The Conference Board, 41.6% percent of Internet users who used Twitter did so to keep in touch with their friends. Yet how many of you have 2,000 friends who have time or care when you get a cup of coffee or watch a movie?

In addition, 29.1% used it to update their status, 25.8% to find news and stay updated, 21.7% for work purposes and 9.4% for research.

Women and men both used Twitter primarily to keep in touch with friends. Secondarily, men were interested in finding news and women in updating their status.

Users under age 35 were more interested in broadcasting their status than their senior counterparts. Older users were more likely to use the service for work-related purposes.

The average Twitter user interacted primarily with friends and family.

Next-most-popular were celebrities, bloggers, TV shows, co-workers, brands and journalists.

More women interacted with friends, family and celebrities than men, but men were more likely to follow bloggers.

Older users trailed younger ones in interaction with every Twitter user type except journalists and brands.

While all of this is interesting data, no one really should be using Twitter except for SEM purposes. I am mean come on, anyone with a real job and a normal self esteem with a balanced self perception really has time to play around in Twitter.

I don’t use Twitter for research as some would argue. If you want to do real research, set up a Google Alert and review the content of the things you are interested in once every few days.

Social media can be the biggest time waster for those who don’t perceive themselves as a micro celebrity or are living in small fantasy worlds.   I meet many people who use Twitter  who are living in a small parallel universe having a conversation with a small set of groupies. It’s almost like watching adults who attended the ComicCon in San Diego this past week, all dressed up like a comic book hero, living in a parallel fantasy universe.  Get a life, get a job, get kids, or start a business and you wont have time to be a celebrity figure in your own private Idaho.

I coach my clients to use Twitter and the other social media tools out there as free  web pages to help their business gain SEM rankings in the search engines, be found by users of the social media world and to stay in touch with a small set of peers.( You may want a profile for each of those purposes). Google and Yahoo search engines are scanning Twitter, Facebook, Google Profiles  and Linked in and your firm should have strong keyword based presences in all the social media streams.

If you spend more than 15 minutes a day on Twitter, you may be one of the following:

1. Unemployed
2. Soon to be unemployed ounce your boss figures out how much time you are wasting
3. Living in your own Harry Potter parallel universe
4. Dying to be a micro celebrity
5. All of the above

Micro blogging at 140 characters at a time is just not space to convey a real message. For that, it’s probably better to blog.
