You also are running into the prior that if someone is trying to sell you something, they are probably exaggerating its claims to make a sale.

Actually, I'm also running into a bias that merely because I have things to sell, I'm therefore trying to sell something in all places at all times... or that I'm always trying to "convince" people of something.

Indeed, the fact that you (and others) seem to think I need or even want to "convince" people of things is a symptom of this. Nobody goes around insisting that say, Yvain needs to get some high-status people to validate his ideas and "convince" the "community" to accept them!

If I had it all to do over again, I think I would have joined under a pseudonym and never let on I even had a business.
