For those who hit my Twitter stream on the WordPress.com RSSCloud stuff from earlier today, here are some collected links with more information:

• The announcement post on WordPress.com
• Dave Winer’s post on the emergence of the tag in WordPress.com feeds
• ReadWriteWeb’s article on the feature addition
• TechCrunch’s article on the feature addition
• Robert Scoble’s mention of the feature addition
• Joseph Scott’s article about the feature, with some examples
• The Plugin Directory page for the plugin that adds the functionality to WordPress.org blogs
• Dave Winer’s site on what RSSCloud is and how it (basically) functions
• Dave Winer’s page on the River2 RSS feedreader, which is able to leverage RSSCloud

That’s all I’ve got in my browser tabs right now; if you see something else, feel free to leave it in a comment and I’ll add it to the list.
