It looks great, I'd love to try it, but I am not comfortable with how many permissions it requires on my Github account.
We don't use those permissions, unfortunately as good as GitHub's API is, their scopes are very limited.

I'd love to try this service out, but I also don't want to hand out oauth tokens that can read my ssh keys.
EDIT: Just read more comments and saw that my github ssh keys are completely public. I guess that makes sense since they are public keys!
If you're not comfortable with the OAuth permissions Gitter requires, you're welcome to try it's sister product, Troupe https://trou.pe. It's got most of the same features, but with less Github integration.
