A lot of our developer docs are Google docs, which facilitate
commenting, and it would be good to keep it that way.
Should we link to those docs from the Apache Impala wiki?

I think that's overkill. There are few documents that don't need
comments (I really tried to come up with one. Something written in
Linear A?)
I also don't think Google docs are really ideal for a shared,
long-lived document managed by a diverse community.
