My point exactly - I understand logging on from hotels rooms, airport lounges, your own office as a brain break, etc. Everyone, and I do mean everyone, at times has to disconnect in order for the little grey cells to remain active, creative and useful.

But to me as high level of PPD certainly calls into question how much value-added business travel/work is being done. I realize of course that not all travel is for business. I realize that more travel means more postings - I do it myself. Also, more experience means (hopefully) more postings in aid of those with questions or requesting help.

IMHO, if I'm running a business, or even a meeting where people are not engaged, and some people are bored enough to wander of into the ether with a high degree of regularity, then I (me, myself & I, nobody else at fault) did a poor job managing and am not doing my job to make sure everybody is actually adding value. If that is the case in a meeting in particular, then the particular topic probably would have been better discussed in the hallway rather than sucking up peoples valuable time. Productivity is the name of the game, not just in manufacturing but also in the white-collar/services world.

Please realize that there are posters with what I perceive to be high PPD whose postings I value and enjoy. Others seem more frivolous. Haven't fully fleshed out fully what PPD would most generally indicate.

Now what would really be interesting is to post not only the average PPD but also the standard deviation, or σ, of PPD. The smaller the σ, the more people would seem to be on "all the time" vs. opportunistic participation as would be suggested by a larger σ.

That would be an interesting new statistic!
