Bix points out that the criticisms quoted by Brent yesterday were actually about the decline of paid, professional blogging.
I reacted to Brent's reaction rather than checking the conversation first hand (there's a lesson here) but feel that position is still somewhat valid.
The rise of the large (social) platforms has, in part, destroyed the market for paid, professional blogging. It is so easy to publish now that almost anyone can do it, flooding the market with thoughts and hot takes on just about everything.
There are so many people willing to write for free.
As Job Gruber said on an episode of the Dialog podcast: "The value of writing has dropped so precipitously."
