> my slightly-less-early-stage business is doing $900 per month in revenue... from ads. It doesn't take much to convert him either! Initially I thought his argument was "I thought using ads doesn't bring any revenue, but now I'm paying for ads and making a net $900" which at least would argue some evidence that using advertising is not useless. However it seems like he's just getting paid $900/month to run ads... so in this case he could have been correct in the beginning and just changed his mind because he's on the winning end of a scam. Not saying that advertising doesn't work, just that his position provides no evidence for that.
