It shows up enough on /questions?sort=active and edit histories that it's not an 'invisible' change, and may even make a difference in helping new users to understand, at a glance, what the heck it is.

Maybe something like this:

From a quick glance around, it looks like there's only two Gravatar accounts this needs to be changed on to take effect across all sites; team@stackoverflow.com (a007be5a61f6aa8f3e85ae2fc18dd66e), and team@serverfault.com (734ca5fe9860e11a8b58aa2c20442781).

Let's allow each site to elect it's own Community Gravator through a vote on each site's respective Meta.

@JayRiggs That would be nice. Unfortunately, since the team@stackoverflow.com address is in use for that account on the vast majority of sites, it would require a change to the Community user's email address to a distinct one per-site to do different ones. I'm not sure how practical that would be; it may turn this into a much more involved change.

How about just using the site's logo? @Shane it would be easy to just use team+sitename@stackexchange.com. That's how all of the sites' contact emails are shown now anyhow. You can manage multiple emails from a single Gravatar account, too.

@nhinkle Yes, I like that idea, but again I'm not sure how impactful of a change it would be to change the email address that all of the existing Community accounts are bound to. I'm shooting for the easy change; if they decide that they'd like to take on the bigger change, then that's cool with me.

I bet they could automate the switch pretty easily... UPDATE users SET email="team+{sitename}@stackexchange.com" WHERE userID=-1

That is a Gravatar, just not a custom one.
