This blog is a topic on the Admin Messageboard.
Please read the guidelines if you aren't familiar with them.
I have just added the new Message Wall Feature. It replaces talk pages for users (not page talk pages). During the next week, we will have the message wall up. We would like your feedback during that time. What you like about it, what you don't, what you're confused about, etc. Feedback will close on Friday February 3rd.
I encourage the other Admins to vote on keeping it or reverting back to talk pages as well, although its mainly the communities choice, as it is such a major change.
