Everyone can’t learn everything. When you watch the news, do you fly down to Maui to interview victims and analyze the state of power lines yourself?
You have to remember where you got something and learn to evaluate the bias of a source, but going on an active forum full of people with various levels of knowledge on the topic is the best way to get a complete picture in a reasonable time frame. They’ll call out inaccuracies in reporting, give background that might speak to problematic motivations or conflicts of interest, and argue bad takes.
Is it perfect? No. It’s DD though, more and more usernames are quoted in the news - hell, even in this video forum posts are referenced frequently
