Some stats to consider:
Jeez, think of all of the valuable things that time could be used for instead of "looking at picture of people I don't know, but did go to high school with". sigh
Never underestimate the "value" of "entertainment", especially on the internet.
How does that figure of about one minute per day for the worldwide population compare to time spent on such activities as talking on a voice telephone or watching television or World Wide Web use as a whole?
