What's the deal with the Google Group
We actually launched our API "quietly" quite a few months ago. We put some initial documentation up into a google group (http://groups.google.com/group/zappos_api) while we got this portal and other loose ends tied up.
We're still porting documentation over. Our goal is to have this portal be the "portal of reference" by September 3rd, 2010. If we don't, you can flame us over twitter zappos_api.
We'll continue to use our Google Group for the mailing list. If you have any questions or thoughts you want to share with our growing community, share them there. We may eventually move to a forum/bulletin board..but we're small and cozy enough right now the mailing list should work just fine.
