Branding and marketing are so important and engineer minded people spit on them and kick it to the back of the line then wonder why their project isn't popular.

Documentation, too. I know it’s hard writing instructions with context you already have (think of the “Tell me how to make a peanut butter sandwich” demonstration), but too often I come across projects that I can’t even figure out how to run. This used to be a complete roadblock if the software was old; now you can at least use LLMs to walk you through it.

Any project that is based on network effects is doomed to failure if it can’t get this right. I think about this kind of thing a lot (and roll my eyes) when I see people on Hacker News complaining about “non-technicals” while assuming they could learn the skills that they have over the course of a weekend.
