The Hardware Compatibility Guides (colloquially known as the HCLs) now have a blog-style page for updates and a directory listing to accompany the existing RSS feed.

The Community-Supported Hardware and Software List
is up and running for vendors and for members of the community to
report working configurations for VMware Infrastructure that aren’t
officially in the official compatibility guides. Submissions do go through moderators, but we just check for appropriateness and we don’t validate these ‘reported to work’ configurations.
