Blogging lesson plans

Boy, do I love snow days. So I finished my two lesson plans today, now only the huge chunks left, like the practicum and portfolio....ugh. But as I was creating my blogging lesson plan, I am having a difficult time coming up with the exit experience part. So, since no one is really posting, thought I'd give you guys something meaty to chew on. My authentic problem is as a worker for antique roadshow you've decided to begin a blog on Depresison era artifacts. This will allow your patrons and fellow experts to learn and add comments. I've required students to post three entries with pictures, description of how related to era and a probing question. I've also required them to comment on three of their colleagues blogs. Sooo.... exit problem? I put down for now that we'd review them as a class, but I know that is way weak. Any ideas?
