Hi Seth, since you're here, can you help explain how the Google+ OAuth relates to the GMail OAuth?
Are they just using different scopes and can you authenticate with both in one go or are they really separate APIs?
Fyi, the /apps link also doesn't work on my account.
It should shortly - the roll-out takes a few hours to get to 100%.
On an unrelated note, thanks for joining HN to participate in this discussion. It is really refreshing to know that Googlers like yourself and Matt Cutts are engaged in their community - it makes it much easier to have faith in the technology collaboration vs. when the movers/shakers sit behind a walled garden.
