I love that they set up a test server for the feeds issue!

On thing I missed in this was if WebSub [1] was considered as an option. Changing RSS from pull-based to push-based fixes many of the scaling problems while still giving readers immediate access to new content.

Many people share this same sentiment that RSS feeds should use a push vs pull mechanism, as if it's somehow going to solve all scalability problems. Both approaches run into scaling issues, they're just different.

Sure, pulling may fix the issue of a server working overtime to fulfill floods of excessive, unnecessary requests. But when pushing, you'll now have to have a strategy to scale and manage having so many client connections.
