Not being an HT Professional, I normally only lurk on this forum. But for what little it's worth, I'd like to comment on this thread please.
First, it took me only seconds to find the definition of "prosumer." (Anthony posted some links already).
prosumer -- noun. 1. A consumer who is an amateur in a particular field, but who is knowledgeable enough to require equipment that has some professional features ("professional" + "consumer").
This is exactly what I presumed when reading Carl's post.
More importantly, why are most of us here on a Remote Central forum in the first place? I thought it was because we are HT hobbyists who want to share information!
Since I'm not in the business, I can't quantify whether replying to Carl's request damaged anyone's income. If this is truly a concern, may I suggest a compromise? Let those who feel a request like Carl's deserves an answer send him the data by e-mail. He gets his replies, the data is not posted to a public forum, "every body is happy?"
