There comes a time when something just isn't relevant enough anymore to justify the amount of time it takes to maintain the code.
RSS feeds is one of those times for me. I've Googled my fingers off looking for indications RSS is still relevant. While I can find advocates for it, it seems the vast majority isn't so impressed with it's chances of survival.
Take this one blog for instance. The author aptly points out many services (mainly Google) has dropped support or stopped the availability of their RSS readers leading to an influx of more polished and/or advanced readers. That's all fine a good, but polishing a turd, is quite frankly, polishing a turd. Additionally, many of the new services and readers require some sort of payment.
It seems to me RSS is on it's way out, still daunting for inexperienced users and/or floundering. It's all really not worth keeping the code maintained when I can offer more tangible benefits such as email subscriptions and automatically posting your blog posts to social media.
While Open Blog v3 is still in Alpha, I've removed all RSS (RSS and ATOM) feeds and started integrating Email Subscriptions (you can see this in action at the bottom of any page here on the blog) and Social Media.
