One of the RSS feeds I’m subscribed to is OPML Editor code updates. Since I run the OPML Editor on my laptop as well as my cloud server, I have a keen interest in knowing the status of the software.
On a near daily basis, Dave Winer, the creator of the software, updates the OPML Editor. Sometimes the update is something small and sometimes it is something big. The cool part is that with every update, big or small, Dave releases the code to all OPML users and adds a comment. Here is an example from the last round of updates as it appears in my feed.

It looks like Dave is working on some Amazon S3 integration. Well, since I also subscribe to the OPML Editor email lists, I already know that Dave is working on deeper integration with S3 but the combination of the email list and feed updates is engaging. It’s like piecing together a puzzle.
Of course, I’m only peeking into a very small portion of the developer’s mind in this way. It’s an interesting way to keep tabs on the software that I use.
