The Evolution of Communication - Writing, too?

I came across this image while surfing the Internet today. This cartoon was drawn by Mike Keefe for the Denver Post. Although it's titled The Evolution of Communication, I couldn't help but post it as a writing reference also. Not only does this emphasize the impact of technology on communication/writing, but it also emphasizes how communication and writing go hand-in-hand. I felt this was important because this is highlighted by the WRTC program. Ever since the first written word, writing has been used as a main form of communication. Although this has been an overall positive trend resulting in more effective and faster communication. However, this cartoon also emphasizes the downside to such trend. With modern social networking sites, where many people communicate through personal writing, many entries have to be cut down to a certain limit. This limits the thought process included in writing. Instead of people thinking thoroughly before sending a lengthy letter to another, they now send almost thoughtless less-than-ten-words responses to others. This has inhibited the writing process to a certain measure. I think this should be focused on when pursuing a writing career in the modern world. Most readers' attention spans have shortened, causing publications such as newspapers and magazines to cut articles down to keep their audience reading. This is an ongoing problem since the turn of modern technology.
