Google Webmaster chat help was a blast! The web ex seminar ran through A discussion of 1 specific site, then critiqued several others. We were given a presentation on optimizing for image search and then had an open Q & A section. The team at google actually stayed overtime on the system to keep answering questions. Additionally, you could ask questions in the Q&A panel and participate in the chat.
I will be posting several mini threads stemming from these topics, so see you later!
