>We need to stop reaching for the easiest data source just because we're desperate for a data source.

I agree. Pretty much all internet sources are inherently biased due to response bias, so there's no fixing that without talking to such people face to face (which is a bit hard in my area).

But if you aggregate enough data you can at least start to see some sort of prevailing trends and sentiments. So I am open to better sources and some biased/compromised forums are still better that choosing to be trapped in an echo chamber. I have browsed around on other comments sections from news sources and the results unfortunately make Reddit look like a think-tank.
