Total Buying Power

Here’s an online media metric for those of you tracking social networking and social media.  Total buying power.  It’s a single, simple, comparative number.  LinkedIn’s average user age is 41 years old with an average household income of $109,000. Its 23 million registered users in May generated 7.7 million monthly visits to the site.  When I multiplied visits by income it made my calculator quake. (It was close to a trillion.)  When I multiplied registered users by the income, the calculator spit the battery. 

In May, MySpace had 60M visitors and Facebook 26M, but how much money do college and high school kids make each year.  Granted Facebook’s average age is getting older, but the income levels really aren’t there yet.  Between the higher income target and the smart marketing strategy, you can see why LinkedIn is the only one of the three turning a profit. 

So, media types, what do you think about this metric?  Is Total Buying Power (TBP) a discussion starter?
