Conference Blog

I'm glad to see that CT is making an effort to boost the level of connection and conversation at the conference through the use of social media. Howwever, figuring out how to make such an effort work can be more challenging than it appears. For example, I note that I am the first to post to the conference blog. Why is that? Is a group blog the right approach for this sort of effort? If so, how could the community of attendees be primed/prompted to take better advantage of it? What else could be done? For example, I noticed that there was some confusion at the beginning of the conference regarding what Twitter hashtag should be used. Would it have been best for the conference to establish and advertise an official hashtag in advance? What else could CT do to boost participation through social media?
