There’s a powerful filter mechanism inside Micro.blog for automatically assigning categories based on criteria in the post. For example, if the post includes an
img tag, assign it to a Photos category. Or if the post includes the 📚 emoji, assign it to a Books category. I blogged about this in September.
Today I’ve expanded this feature to also allow matching on whether the post is a short microblog post or whether it’s a longer post with a title. Like other parts of Micro.blog, it uses the title to determine how to categorize the post. Posts without titles are always considered short microblog posts.
To create new filters, go to Posts → Categories → Edit Filters.
You can use this in combination with matching the title or text in a post, or leave those fields blank when creating a filter to match all posts. This makes it easy to move all full-length posts into a category, which can also have its own RSS feed.
