Yes, astral is a great tool. But our goal is different. We're trying to crowd source the tagging work so that most people don't have to tag repos any more. And the tagged data could be used by any Github related services or anyone who wants to study open source projects.

I guess the point is, whether you want to tag everything yourself, most of the tags are really standardized anyways. Probably a standardized shared tagging system that allows some personal touch would be the best.

Author of Astral here, it is currently open source (http://github.com/astralapp/astral), but a bit of a mess since I'm trying to upgrade the stack and fix some bower dependencies. Hoping to get it tidied and ready for real contributions within the next month or so.

Oh, I guess maybe this open-sourced a little after launch? I looked around for the source when it was first launched and couldn't find it.

You're correct, the decision to open source it was quite recent. I'm excited to see where the dev community will take it once the repo is in good shape :]

And this is why I love open source and HN.
