Susan Moskwa & Maile Ohye and some of the more well known Googlers who are great out webmaster outreach - they go to many of the US based SEO/SEM events.
Unlike JohnMu, Jonathan Simons, Pierre Far and some other Googlers, when Maile & Susan do Google Webmaster Hangouts, they do so as a team - a duo. So the conversation is a bit more interesting when you have two Googlers as opposed to one. The only issue, since Google Hangouts fit up to 10 people, you can only get 8 webmasters into the Hangout to participate, as opposed to when only one Googler runs it where you can get up to 9 webmasters.
That being said, the hangouts are often fun and if you can get in, it is often worth while.
Today at 1pm PDT or 4pm EDT, Susan and Maile are hosting another hangout. I wanted to give you webmasters and SEOs a heads up so you can join, if you are one of the first.
For more details, see Susan's Google+ post on how to join.
