The belief that there is some kind of market-impacting underground "wisdom of the crowd" to be found on all these public social platforms is an artifact of the GameStop craze that never went away.

It existed prior to GME as well, which really should tell you that anyone who is using this is going against people who have spent the last decade at least perfecting signals based on this exact same data.

The hope isn’t that you find some unique signal to trade on. The hope is you find some signal that does not scale in a meaningful way, so it is less likely professional firms are going to devote resources to trading it.

If you stumble into a fresh, scalable signal it’s unlikely it will continue to be profitable after six months. Once you scale to any real profitable size the market will notice and either change behavior, or trade the same signal at a faster speed.

Twitter/fb/reddit etc is like the towel that gets the water after it already spilled, while the hedge funds or advanced traders already placed sensors at the entire pipe to detect the leak.
