Even back in the Usenet/Newsgroup days of the Internet there were two kinds of people online; joiners and lurkers. As we've grown in sophistication in social networking, so has our ability to more finely discriminate between the types of people that we network with. Now Forrester Research has come out with their "social technographs ladder" which divides Internet users into 7 basic types. Take a look.
If you take notice, the ladder adds up to more than 100%. That's because
most people fall into several categories at the same time, depending upon their level of
comfort in an area or social circle. I expect the ladder to become even more finely delineated as we go forward. Which categories to you fit into?
