I've joined a few discord study groups/software projects from 4chan before. 99% of them fail after a few months. The reasons why it never builds into a functional, high performing community
>unrealistic expectations
People largely go in expecting a fully functional, engaging community but the reality is you're getting a mass of untrained, unmotivated and unrealible people who's here out of fleeting curiosity. Most people are too lazy to organise and push themselves to do anything.
>discord servers lack any sort of structure, duty or accountability
Because everyone is uninterested and unmotivated, the community has to serve as a structure to hone and train each individual into achieving their own goals, because on their own they lack the will to. But online and 4chan in particular attracts a kind of disgruntled above average intelligence young male that hates duties, rules and cooperation because they have a sort of lone wolf genius image of themselves. Fine for an anonymous forum, but anathema to building any sort of organised effort, which fundamentally is what such communities are.
>no sense of direction
Most of these communities, having no real direction or leadership, quickly fall apart as time goes on and nothing is accomplished.
Quant is not simple stuff, it's very high performing, demanding knowledge. Producing people to do that needs an equally high performing, demanding community that can demand, get and sustain a high level of focus and participation from them. But most people are inherently lazy.
I'd love join and set up a community that can do this, if we can agree that these problems are real and need to be solved with ingenuity and effort.
