One of my favorite resources is the IndieWeb wiki page for RSS as it’s got some good pros/cons, alternate methods for feeds that don’t require side files, conversion tools, and miscellanea.
I’ve always loved the way that platforms like WordPress provide RSS feeds for so many moving parts including authors, comments, dates, tags, categories and various combinations of these. This is a bit reminiscent of Huffduffer, a bookmarking site for audio and podcasts, that provides RSS feeds for almost every portion of its website.
XSL for creating human-readable OPML & RSS feeds is an interesting quirk I’ve seen a few times in the wild with interesting results and design opportunities.
Of course you can’t get away with writing an article without referencing http://isrssdead.com/. The favicon on the site, which ironically doesn’t have an RSS feed, leads me to believe that it’s owned by Dave Winer, the creator of RSS. It seems like it is giving a nod to http://isabevigodadead.com/, but given the site owner, I don’t think it will ever indicate “yes”.
One of my favorite RSS tangential topics is OPML and OPML subscription. There’s nothing more fun that auto-updating subscriptions of bundled RSS feeds.
An interesting, underreported, and discussed phenomena I’ve noticed over the last few years for many websites that do have RSS is that they’ll change CMSes and redirect all their URLs properly for SEO purposes, but they completely neglect to redirect their RSS/Atom/other feeds and thereby lose all their subscribers or force them to manually fix broken feeds. It’s the sad equivalent of creating a new Twitter account and then trying to regain all of one’s followers one at a time–and a simple thing to fix.
I’m watching your RSS feed for your take.
