After much deliberation, I've decided on a new name for this project. MeTal is now Mercury.
For the sake of SEO, you can use the term "Mercury Blogging", or "Mercury Blogging Python" to be totally unambiguous. (There is a "Mercury CMS" out there, but it's a legacy product not updated since 2005, and not a blogging tool.)
The old domain name will continue to point to this blog indefinitely. The new domain is mercury.genjipress.com.
The repository name and a few other things will be changed over shortly. (Update: The new repository is now live.)
Look for more news soon!
