What about the case where getting the work done involves doubling the number of people involved in the project, and not a single line of code?
Nobody's on the fediverse, and email is not taken seriously by most modern developers. These interactions still happen on the web.
It’s the only social media I use, and it’s a ghost town. We have to live in the world that is, not the one we wish were.
I used to have a Twitter follower count on my niche little tech/privacy account that is higher than the DAU count of the entire fediverse.
No, it's nothing like Twitter in terms of DAU. However, your Twitter account compared to your Fediverse account is not a good representation of the entire state of the Fediverse. And: it's not necessary to capture 100% of the market share on attention. It's simply necessary to capture enough that your project is successful.
GitHub is explicitly designed like a social network, and this is a design that we reject. Counting stars and scrolling through feeds is a distraction from getting work done, not to mention an unhealthy relationship to have with your work. Popularity is not a metric we think that people should be optimizing for, or one that can even be effectively measured.
So our design deliberately skews away from what we think of as "dopamine dispensers" and instead focuses on getting the work done. We make it easy to onboard new collaborators by skipping the account requirement to send patches or file tickets. The UI is simple and accessible for users with any accessibility needs, and free of distractions. Colors are used deliberately to attract your eye to the action items on each page, not to dazzle you with information overload. These are the kinds of motivations which guide the design of the platform.
For the social aspect, we encourage you to branch out. Talk about your project on Hacker News. Maintain a fediverse presence. Put up a marketing page and documentation on SourceHut pages. Cultivate welcoming mailing lists. There are many ways to crack an egg.
