Every year there are some great folks that blog from SYMC. I always get some great info and input 
from these wonderful folks that are able to go to workshops that I could not attend. If your blog posts just talk about the overall experience at SYMC, that is great too. So far, these are the blogs that will have live content during SYMC:
