Al Bell and the long tail (or tale)

Mike Kilen, a reporter for the Des Moines Register called me a week or so ago to talk about an old blog post of mine that has gotten a lot of response. (Mike's article is here: What Ever Happened to Al Bell? Inquiring Facebook fans want to know.)
The post, "Did You Know Al Bell" (Jan 29, 2007), wasn't about technology or libraries. It was an off-hand remembrance of a fellow who came to small Iowa schools to give "assembly" programs back in the 50s, 60s, and 70s.
As of today, this small post has generated 159 comments - nearly all from Boomer generation Iowans who shared fond memories of Mr. and Mrs. Bell's travelogues.
The "long-tail" theory says that no matter how obscure the topic, there is a group of individuals interested in it (and a market for it). From now on, Al Bell will be my true-life example of the long tail.
But I believe the real lesson to be learned here is just how great an impact single educators can have. Comment after comment to the post remark on how Al Bell opened the eyes of small town Iowa kids to a larger world, making global traveler and citizens of many of us.
Next time you go home thinking your teaching day has been a disaster, that a career in selling industrial chemicals would have been both more rewarding and lucrative, and you wonder if anything you've ever said to a kid has made the least difference, think of Al.
I suspect all teachers have a greater and more lasting impact that we will ever know.
