I ask real people on social media what they think. Sure, there may not be a niche community for every little thing on Lemmy; but there's also not the same level of rules limiting what can be posted where so I could make a post asking everyone what they recommend for whatever in NoStupidQuestions or AskLemmy or whatever and still reach a respectable number of people who could give a response. 🤷🏻♂️
