I use RSS to read news and having a single place with blogs relevant to Elm is very convenient for me. That said, you’re right that it hasn’t really taken off, so if there is any amount of inconvenience in running it I would understand you shutting it down.
A couple of points: firstly, I am a user of RSS and probably about the most likely user of planet-elm, but I didn’t know of its existence until this thread. I wonder if it could be added to the ‘Community’ page at: https://elm-lang.org/community?
Secondly, the “Subscribe to RSS” link is right at the bottom, when I first went there I didn’t see an ‘RSS’ logo, so I just put the home address into my RSS reader (which normally automatically scans and grabs the address of the feed), this failed, so I assumed RSS was not a feature of planet-elm. Only later when I browsed down to the bottom of the articles did I realise I was wrong. I’m now subscribed
It has always surprised me that someone hasn’t done a ‘planet-planet’, which would allow people to set-up and maintain planet sites for any topic of their choice.
