The folks who are responsible for Webmaster Central, the old Google Sitemaps, announced at the Google Blog that they have a blog specifically for Webmasters at http://googlewebmastercentral.blogspot.com/.
This blog will be more focused on the technical side of things, from what it appears. Currently, the blog has topics on feature enhancements to Webmaster Central, googlebot tips, system maintenance updates and more.
