Interesting article over at the Guardian Unlimited. They are estimating that when folks get online, 1 percent of the population creates the content. About 10 percent will interact with it (comment or offer improvements), and the rest will just read or observe it.
That means that all of that nifty stuff out there is done by the few. So get cracking and add your own two bits. Join the elite. Become a part of the few, the proud, the producers… :)
