Most Open Source projects die. That's why CPAN, PyPi etc. are able to have such a huge number of packages, a significant part, if not most, has no documentation, tests, support or is dead all of which in practice is more or less the same.
"In the old days" you didn't notice it as much because those projects just disappeared but with Github they don't, in fact they're all over the place.
I'm not sure if this is a problem or one big enough worth caring about but in any case Github isn't the problem.
It would be nice if authors could "archive" or "abandon" repositories which could be filtered out on searches by default and be displayed less dominantly on profiles.
