Google has been holding frequent webmaster chats using Google Hangout. It seems they do a few each week.
Those on in the states - Google is hosting one day at 4pm EDT / 1pm PDT on Google +.
John Mueller posted the details on his Google + profile.
The topic includes: Anything webmaster related like crawling, indexing, duplicate content, Sitemaps, Webmaster Tools, pagination, duplicate content, multi-lingual/multi-regional sites, etc.
If you do not know how hangouts work, A hangout here on Google+. It works best with a webcam + headset. You can find out more about Hangouts and how to participate at http://goo.gl/tWc3b.
So check back over here at 4pm.
Who knows, maybe GoogleBot will join the hangout too?
