A blast from the past: I have an RSS feed and it's available at seblog.nl/feed.rss. (I also have seblog.nl/feed, which is actually the h-feed version of it.) I made the RSS feed a while ago for Martijn, who I believe is my only subscriber at the moment.
Back when I made the feed, I didn't want to put in much work for it, because I already have a couple of rich h-feeds. So I made it so that "if a post has a title, give that, else, just call it 'post'" and "if a post has content, give that, else, just say 'A post on Seblog'". Very lazy. It turns out I actually have a lot of posts that have neither a title nor content. Things like my likes, reads and bookmarks all have no title nor content, because it is stored in different fields. So my RSS feed ends up being filled with contentless posts.
I am still lazy about my RSS feed, but I improved it a bit. I now just call the same snippet that produces the HTML for the frontpage for the content of the feed item. This means the whole post is in the RSS feed. Probably not the best way to do it, but hey, who uses RSS nowadays anyway?
@martijn, let me know how it looks!
