Lots of things changed between when I started to heavily and systematically consume content online (in about 2006), and today. But one thing didn't: RSS is still the crucial cornerstone of my online content consumption.
For me, RSS never was dead or less relevant than in the past. On the contrary: Since I keep adding feeds on a very regular basis, it's still growing in importance.
Fortunately, 95 % of blogs and media sites still provide RSS feeds. As long as this is the case, RSS will remain crucial to me.
