I have come to find that there is an age line that can be seen in how a blog is designed. (An author designs their blog by how they envision their readers interacting with it.)
Generally, people above this line design their blogs to be read on a computer, and people below it design for a tablet or phone.
I would wager that the same is, and has always been, true with everything… including politics, foreign policy, and economics. (Although, in this time of great change this reality is far more significant than it ever has been.)
How silly it would be for me to fight with a younger person to get them to design their blog for a computer instead of a tablet.
