I just registered, and I wanted to revive this discussion about Backspace. My only experience with the industry is limited to my participation at AW, so I'm really nervous about going. Will I stick out like a newbie? What to expect?
You will love it! (I think). I went for the first time in May and it was an awesome experience. I would sign up for a few of the 10 pages sessions, especially if you're shy. It will give you a chance to get your MS in front of people without having to tug on their ear after a panel.
I met the members of my YA writing group there. The people were nice and the information was great (although, if you've been doing your research, a lot of it will be a rehash of things you know). I especially recommend attending the final day , if you can. The writing workshops I attended with Robbins and Maass were excellent.
Oh, one more thing. I met a few of the people in advance by looking over the names in my small workshop sessions (for whatever genre you're in --they'll email them out ahead) and Googled them. I contacted the individuals through their blogs and knew a few people before I arrived. It was nice to see a few friendly faces...er...gravatars.
Best of luck to you!
