The strictly horizontal nature of the movement had its upsides and downsides. It allowed the movement to swell extremely quickly, but the more the movement swole, the less agile and focused the movement became. Individuals were able to respond to individual situations rapidly, but the movement was completely incapable of making decisions, producing an official line, or reacting to shifting media narratives with anything approaching the urgency which was necessary. As an alternative to working out our internal contradictions, we left these issues unaddressed.

You seem to have a lot of experience with this, so correct me if I'm way off base, but it sounds like there needs to be a lot more discussion and work put into analyzing organizational structures to determine what is effective and what isn't, while also following ethical guidelines as much as possible to avoid unnecessary/unjust hierarchies and maintain democratic decision making? Seems to me like this is possible, but would require better knowledge of how to operate within those organizational structures, and I don't really see that being discussed much in online leftist spaces. Technology could also help, with things like DAOs serving as an organizational backbone that is less reliant on centralized authority.
