In your opinion, which FOSS software is by many considered "old" or "obsolete", but are in fact, in your opinion, in many ways better than the newer alternatives?
Do people not use it anymore? I still do. I follow a boatload of different youtube channels, webcomics, blogs, etc. If there's some other way besides RSS to have all of those updates show up on a single page, I don't know it.
That's what I used twitter for tbh. Since everyone is on it it's easy to follow people, get instant updates and maybe even discover something new through the people you follow and their likes. It's really a shame it went to shit, it was the lurkers perfect tool, especially when it comes to artists or content creators.
