Ads are an odd concept—it’s someone paying money to toot their own horn, which most of the civilized world looks down upon. In fact, the best way to sell me your product is to have the humility to tell me its downsides or give me a nuanced explanation of when to buy your product vs. a competitor. Otherwise, it’s always much better to let someone else sing your praises. I do find documentation, videos, and other factual information about a product to be the best possible sales pitch—give me an accurate picture of it, and if it’s really any good, I might just buy it. If I think you’re trying to bullshit me, I’ll assume your product has to be shit, or otherwise you’d just tell me the facts.
