I was expecting a more pragmatic explanation of why Clojure, Mac OSX and Google App Engine. Although at this point, the pragmatic selection of Mac OSX and iOS is understood.
What did Clojure do for you that the hundreds of others don't or didn't? What is unique about your infrastructure? What challenges did you find? Etc..
Why the Google App Engine? Cheaper? Free? Faster? Why not the others?
The post was already quite long, so I tried to summarize everything. I will reserve this part for another post in the future, also because for now the apps are not yet live and I will certainly have more experience in the future to address all these questions better.
i know its not git, but bitbucket (mercurial, same type of dvcs as github) has free private and unlimited repository hosting.
