It need not become one to be a problem (just as it is a boon). The benefit of frictionless contributions is real, the problem of loss of federation is real just as much, and leads to the loss of community. We're animals. The feeling of community arises when we're not alone yet feel being in private. Community is us (versus the rest). Github is a faceless "everybody" (vs. nobody left), which on the animal level translates to "me" (vs. everybody else). It was easier to maintain a tiny community in the times of janky sites with mailing lists and diffs emailed around. Github gives you access to a larger pool of potential drive-by contributors, but you can't create a loose ring of a handful of people in /issues and /pulls. The community arises through people joining, and then failing to leave, a mailing list, and then contributing to the project through occasional replies to questions asked by beginners. There may be seven long-term subscribers to your niche project's mailing list. When a newcomer shows up with a question, one of them might answer it before you get up. And even if they don't, their continuing passive presence on the list is still a currency that helps you push the niche project further. Stars on a github.com repository just don't carry that much weight. Seven people might star your niche project repo. If they use their "dashboards", the entry for the new issue (the newcomer asked a support question by filing a ticket since you have no janky old school mailing list) got lost among the other tens and hundreds (even thousands) entries for individual commits and comments in repos those people have starred beside yours. They won't answer that support call for you. And, even if they did, they won't feel being part of any niche project's community either: it was just a drive-by comment on a random issue they spotted on their feed... tldr: github.com is the largest open-plan office in the world.
