I have always been a proponent of websites publishing #feeds for their content. My own website has feeds for almost everything on it (https://abhinavsarkar.net/feeds/). But till now, it only published latest few items in each #feed.
I also extensively use #FeedReaders to read many feeds. I noticed that while subscribing to people's feeds, I find myself looking at their older posts published years ago, and often find interesting stuff in them. So I've decided to remove limits from the feeds on my website, so that it shows all my posts ever.
I hope people find something interesting in my old posts as well.
