Webmaster level: All
The TC Summit was a blast! As we wrote in our announcement post, we recently invited more than 250 Top Contributors from all over the world to California to thank them for being so awesome and to give them the opportunity to meet some of our forum guides, engineers and product managers in person.
Our colleagues Adrianne and Brenna already published a recap post on the Official Google Blog. As for us, the search folks at Google, there's not much left to say except that we enjoyed the event and meeting Top Contributors in real life, many of them for the first time. We got the feeling you guys had a great time, too. Let’s quote a few of the folks who make a huge difference on a daily basis:
Sasch Mayer on Google+ (Webmaster TC in English):
"For a number of reasons this event does hold a special place for me, and always will. It's not because I was one of comparatively few people to be invited for a Jolly at the ‘Plex, but because this trip offered the world's TCs a unique opportunity to finally meet each other in person."

Herbert Sulzer, a.k.a. Luzie on Google+ (Webmaster TC in English, German and Spanish):
“Hehehe! Fun, fun fun, this was all fun :D Huhhh”

Aygul Zagidullina on Google+ (Web Search TC in English):
“It was a truly fantastic, amazing, and unforgettable experience meeting so many other TCs across product forums and having the chance to talk to and hear from so many Googlers across so many products!”

Of course we did receive lots of constructive feedback, too. Transparency and communication were on top of the list, and we're looking into increasing our outreach efforts via Webmaster Tools, so stay tuned! By the way, if you haven’t done so yet, please remember to use the forwarding option in the Webmaster Tools Message Center to get the messages straight to your email inbox. In the meantime please keep an eye on our Webmaster Central Blog, and of course keep on contributing to discussions in the Google Webmaster Forum.
On behalf of all Google guides who participated in the 2011 Summit we want to thank you. You guys rock! :)
