Everywhere where there is incentive difference there are problems. Why would anyone go on producthunt and browse new products? When I need something I google.

Everywhere where there is incentive difference there are problems. Why would anyone go on producthunt and browse new products? When I need something I google. But having a vanity plate on landing page "product of the day" gives social value, so product creators abuse the system. Same thing goes for reddit reviews. If you go to any subreddit multiple times a day someone would ask for a recommendation. Normal user might spent 5 seconds answering "I use product X. Its good". But if I am a marketer in firm making X, I can write long, seemingly unbiased overview, then mentioning X is best. I get paid to do so.
