I asked a question some days ago in stackoverflow that involves generating a custom widget for android.
I just edited my answer adding some code I did so far and I used someone else code as well. I didn't paste it all in the question because I didn't want to use all the space with code.
I was willing to place the code somewhere people can edit or propose patches.
So that's why I would like to have this. Each question having a repo (svn/git/whatever) where people can upload code and get improved by the community.
What do you think?
PS: Accepted patches == rep points? :)
