There won't be an Apps and Projects section [for other sites]
What about other technical/programming sites, like Code Golf or Programmers? What if I want my projects to be there?
A possible solution is a site-specific section there. It could be GitHub for programming-related sites, a recipe site or something for Cooking, etc.
Or, it could just be called "Projects," and it is made by the user, who provides as many links as he/she wants in that section. This is also advantageous as people could post blog links, other projects not on GitHub, etc. This would also be good because I could post only my code golf repo's from GitHub on Code Golf.SE, and exclude them from SO.
