I block ads, nuke cookies, and use old.reddit.com exclusively, but somehow I still manage to spend a lot of money on shit I don't need. Most of it was found on reddit. All of it got a google search that included "site:reddit.com" before buying. This anecdote is not unique. The fact that reddit gets $0 despite being part of my typical buyers journey is a failure of Steve Huffman, not the users.
If Reddit automatically added product links to comments like Viglink did in the bad old days, you wouldn't be using it. Reddit's failure to capture affiliate revenue is precisely what prevented it from being gamed, thus making it a credible source of information.
