"Well, let's not forget that the pay-off for that particular thought experiment was relativity. :)"
I agree :-) . But even Einstein didn't know what he would end up with before the thought experiment.
"I (and possibly others) would probably be a little less cranky about the whole article if he'd followed his steps rigorously and arrived at something interesting."
I agree that the article is completely tangled and confused and not worth the time spent reading it. I was just using the question posed (and ignoring the source and the accompanying article) to do some thinking to see if anything interesting results.
