Talk:Github vs Wiki
More Wiki Cons?
In the Wiki I, as a reader, never know what is current or obsolete. There are a lot of pages in a flat namespace, laced with links to google docs. As an outsider I have a very hard time orienting myself. In a github (or git repository in general) I have multiple repositories and branches within repository, I have tags for releases (builds), I have branches for forks (replications). I can imagine a repository for 3D printer for example, where the master branch is work-in-progress towards the next build, while past builds are tagged as such. To replicate a any past build is easy in such a setup - I clone the repository and checkout the tag of the last successful build and everything is at my finger tips. It works for software, there is no reason this cannot work for hardware as well.
I see this as one of possible reasons while there are not more replications.
