Thing 13 is here and it's Google sites. I've played around with this a bit before. We have a site for the ECS (Electronics and Computer Science) librarians. Also, this is where our Academic Liaison Librarian profile pages are kept.
However, in the 23 Things spirit, I have created a brand new site about my visit to Lund.
I do find Google sites slightly frustrating at times but it has lots of useful features, such as being able to add Google apps to pages.
