The really cool thing about OPML files, that some feed readers and clients support, is that you can subscribe to the OPML file itself. This means that you’ll not only get the posts of anyone included when you subscribed, you’ll also get the posts of anyone who is added to the file at a later date. As the list of of feeds grows, so does the number of blogs and posts you’ll see.
I was not aware of this. 👀🤔
