I’ve seen this shift in my own usage. I find myself appending “Reddit” to the end of my searches a lot more often, I have pinned Wikipedia to the top of my search results (in kagi) and I haven’t visited stackoverflow in months, although I see that perplexity quotes it quite often when I ask it coding questions… I’m just a sample of one, but it’s certainly interesting to see how apparently I’m just one of many
I also used this tactic for questions about certain products, but I no longer use it in general because reddit has become riddled with bots, AI stories, astro-turfing campaigns, etc. It's hard to come across something genuine any more. This has been the case even before the AI craze of course, but now it's virtually unavoidable. The whole platform has become a giant shit hole.
If I’m shopping for something deliberately enough to be digging through reviews I’m probably pretty sure it’ll solve the problem all the positive reviews say it will solve. But I want to weigh that against all the negative feedback that might be removed or downplayed in big marketplaces or commercial review sites.
