The Micro.publish plugin allows Obsidian users to easily publish their notes to a Micro.blog blog. It supports customizable settings for multiple blogs, including post visibility and categories. Users can publish posts directly from Obsidian using the 'Post to Micro.blog' command, and synchronize categories between Obsidian and Micro.blog. The plugin also supports YAML front matter or Properties for post titles, tags, and metadata. Additionally, users can edit and update published posts by linking them with their corresponding URL. This plugin streamlines the process of integrating Obsidian with Micro.blog, making it an efficient tool for bloggers looking to publish content directly from their notes.
