Whenever I see things like "Why duplicate the effort, help with the existing ones", I cannot help but wonder how people fail to recognize that all great things had once a beginning. Gogs may or may not turn out to be great, but thinking that because it duplicates effort, it's a waste is very short sighted. Examples? How about countless Linux distributions? How about git itself?
You obviously didn't read the README section titled "Purpose". Here's a copy:
``Since we choose to use pure Go implementation of Git manipulation, Gogs certainly supports ALL platforms that Go supports, including Linux, Mac OS X, and Windows with ZERO dependency.
More importantly, Gogs only needs one binary to setup your own project hosting on the fly!``
But even if "all it aimed" was to be a duplicate in another language, that's just part of what will define it in the future. Linus didn't "aim" for his "just a hobby, won’t be big" project to take over the world and it did. Public open source projects have some of the most unpredictable paths - I'm not sure why you're trying to imply this one's an exception and it'll go nowhere!
