Personal servers are more prone to intermittent operation, caused by things such as an OS upgrade gone bad and the owner not finding the time at the moment to fix it. If on the other hand you have a repo on GitHub that one can go get then users will know with much greater confidence that the repo will stay available at all times for the foreseeable future.

I run my own web and mail servers, but the canonical repositories for all my code is on GitHub, both because then I know my code is always available to myself but also because I know that it means that others will have fewer reasons not to use my projects, because even though I know that my uptime and stability is good, others can't know that, but they know that GitHub is.
