You're both arguing by anecdote here. It seems to me self-evident that Github has many more projects on it -- not just forks of existing projects, but original projects, period -- than its predecessors and competitors do. This just about definitionally implies that it has a lot more crap. While it would be hard to prove that Github has a higher percentage of crap on it than its predecessors and competitors, that's certainly plausible.
However, you're essentially taking it as a given that the absolute number of worthwhile projects has dropped thanks to GitHub. If there's convincing evidence of this, I'd honestly like to see it, along with a plausible theory as to why that would be the case. What does, for example, Sourceforge get right that GitHub doesn't? (At least from my anecdotal experience, Sourceforge is in fact full of under-documented, unfinished and effectively abandoned crap to more or less the same degree that GitHub is.)

Not just dropped -- they're drying up. I can only speak from anecdote (nobody has paid me to run a study), but while I've seen no dip in usage of my libraries, and I've seen my projects explode with half-baked forks on Github, I've seen mailing list participation and worthwhile code patch submissions drop to very nearly 0.

SourceForge essentially died out for modern projects upon the release of Google Code in 2006.
However, what (traditionally) SourceForge and Google Code did right -- and, what projects did in their own hosting for decades before and after that -- was place the project's community in the forefront, and the code in the background.
This meant that documentation, releases, mailing lists and other constituents of a vibrant community project were placed in the forefront, with the code being something that one worked on as part of the community.
By contrast, Github made projects secondary. The code was (originally) always attached to an individual account name. The primary project page was the code itself. Forks existed at the same namespace hierarchy as the projects they forked.
The result was that Github sucked community energy into Github itself, and in doing so, began to redefine the community social constructs in a way that allowed users to maximize social and personal rewards while minimizing work necessary to conform or participate in the project's community.
