I think there's no shortage of active investing threads/discussions on reddit, YT, various blogs, Seeking Alpha, yada yada. Stock picking, market timing, options speculation, crypto speculation, technical analysis - you name it. It's all there. The debunking is always harder to find than the entertaining stuff content creators make money on.
BUT... as people are starting to learn about Web 2.0, most information in these spaces exists to drive traffic to ads. There is a huge economy of "influencers" earning revenue from ads and endorsements by providing horrible or semi-fraudulent investing advice or economic information on the internet. If you're a 24 year old English major living in your childhood bedroom, then you too can rebrand as an investment advisor or economist with 20 years executive experience who creates content out of the goodness of your heart to help other people with their day trading. But essentially all these people work as influencers.
I've given up all social media except for the MMM forum for a few key reasons:
1) The MMM forum itself has no ads, no endorsement deals, no affiliates, no pump-and-dumps, etc. It exists in the old Web 1.0 world, free from the distortions of the algorithmic attention economy (in which truths cannot be communicated if those truths are boring). I've learned that consuming trash information from social media has negative impacts on my decision-making, contentment, and finances.
2) Instead of professional "influencers" vying for ad spending by talking about investing, this forum *seems* to be populated by "doers", including actual millionaires and FIRE people. These sources are simply more credible than social media influencers, even if they are not as entertaining.
3) There are lots of perspectives here with intelligent backing. It is anything but an echo chamber. I'll occasionally check out the echo chambers on Reddit, SA, and various blogs and it gives me goosebumps watching people repeating a dogma to each other over and over again, and then throwing down large sums of money on such bets in a public display of fealty to the cause and faith that reality will someday match the theory. It's. A. Website. People. And then they blame someone else or come up with a conspiracy theory when the price of gold, GME, dogecoin, or whatever decreases, contrary to expectations. No thanks.
The MMM forum as it exists offers something extraordinarily rare: A place where the people actually doing this FIRE thing (as opposed by entertaining others with thoughts of doing it) can compare notes, learn optimization skills from each other, ask questions, and opportunistically explore new ideas. Yes, the person who walks in here with a bullshit get-rich-quick scheme usually gets a facepunch, but ideas that have merit will survive the gauntlet. In other words, the lack of a safe space or a criticism-free zone raises the quality of everything. Even people who walk in here promoting their own ad-plastered blogs get facepunches, and that's great!
It wouldn't be the end of the world if we had a "speculation zone" for the single-digit percent of one's portfolio that is allowable for speculative gambles or trading strategies, as long as the expectations for behavior didn't change once you went into that folder. It would be messy to communicate that; people already don't read the stickies. Might be just as straightforward, and more reliable, to clarify in each post that one's active investing is with their speculative AA.
I also worry you'd eventually have people YOLOing their whole portfolio in that space, or advocating market prediction voodoo like technical analysis, and it would begin to look like the rest of the shitternet. Then again maybe a facepunching shooting gallery like that would be fun in its own way, while helping people avoid scams and investment fads.
