There are quite a few git hosting sites mentioned on http://git-scm.com/tools.
We group of enthusiastic developers are willing to learn android app developement and Google App engine as cloud power.
So we have decided to create an android app.
Initially I was thinking to create it as opensource project for which github.com is perfect hosting place. But now we are not making it as opensource. ( May be we can consider it making opensource in later phase )
bitbucket.org gives free pivate git hosting. We will be trying it.
Stay tunned on this python blog for more updates.
