We all know you shouldn't use the cell phone, while driving a car. It is not really possible to 'split' your attention between two activities, and still do them as well as you could, one at a time.

But it works the other way, too. Any activity on a mobile device is also impaired, if you're splitting your attention with other activities & environments. You can do better computer-work, of any kind, at a regular computer-station. True rumor.

You can engage in passive consumer behavior with a mobile device while distracted, without penalty, but not so with anything creative ... and of course, that's a 'feature', not a bug. Biz-wise; passive-good, assertive-bad.

Social media and mobile devices involve some hefty dumbing-down. Hopefully, the fad-aspect of it cools and many return to (or discover for the first time) the pleasures of being the digital actor, instead of the audience.

Certainly, there is plenty of history that supports a fad-basis for currently popular digital products. Many things have been very hot at one point, and then subsequently not at all. Many think a new day will dawn, yet-again ... but it probably won't be a day in 2007, or 1999.

If the headlines tomorrow are Facebook: RIP, that doesn't mean we go back to pre-Facebook WordPress. Etc.
