seems like a perfectly reasonable idea for a blog about different stacks. I'm not advocating it, but there's nothing wrong with it if that's what interests you.
OP is saying don’t be the person who says they want to write about Frogs, but who then spends an immense amount of effort not writing about Frogs, and writing about procrastination instead.
Almost every opinion people have has been covered by someone else in some way unless you are working at the forefront of something, so it usually depends on how you value-add to existing things with your own experience.
It's also that sort of I-know-what's-better attitude that turns a personal thing into a competitive thing.
What is semi-successful anyway...
