We have moved beyond "generation gap" differences in technology use and moved into the "experiential gap" in terms of use and understanding. Your experience with an application such as Twitter provides an understanding that cannot be communicated by reading about it or even being told about it.

Tom Foremski recently penned on twitter in which he notes the growing experiential gap that separates those who use new social media tools from those who don't. Those who use, get it, and those who don't, don't. Well, not surprisingly, this digitally dividing line is also the void that old media needs to bridge, if it, like its users, are to join the ranks of the initiated. The adoption curve sweeps like the arc of a #suspension bridge (!) plotting the line of escape from the old and tired traditional media landscape to the bright and shiny shores of the new.

The "content" of any medium is always another medium

The content of writing is speech

just as the written word is the content of print
