Thanks for all the feedback.
@benali72 - your link was very helpful. This standard is most useful in very large companies. My target market is mom and pop businesses. I suspect if I had it in my credentials, most would say "so what?". OTOH, since my creds and skillset get farther out-dated with every passing moment, I need to add something "official" to get past the current crop of gatekeepers.
One of my favorite comic strips growing up was a "Peanuts" panel that showed Charlie Brown's sister, Sally, sitting at her school desk with her hand raised to called on. I don't remember exactly how she phrased it, but she pointed out to the teacher that she had been sitting there for a time and had learned nothing new. "Since Nature abhors a vacuum, I may even be a little dumber than when I got here."
It would probably be a better use of my time to "learn" something else.
Still interested in your opinions, though.
