I agree, and I don't think they're actually dying. I think certainly they're a much smaller percentage of consumed content today than thy were 15 or 20 years ago, but I don't believe that's because readership has dropped. It's just that the pie is significantly bigger now, and other media has gobbled up most of it.
I dropped off social media 5-6 years ago and don't miss it; I still read blogs and get much more value out of them.
