Must every blogger have a post about blogging? Rather predictable isn't it. Well here's mine anyway.
Every mea culpa for a mea culpa should also have its own mea culpa. This one doesn't.
A blog is not just a piece of opinionated writing. It is also not just a piece of opinionated writing which comes from a position of ignorance. It is not just a piece of opinionated writing from a position of ignorance which does not exist in hardcopy. A blog is a piece of opinionated writing from a position of ignorance not in hardcopy which will disappear within a decade. Count on it! I'm sure of it! I'm right!
It's difficult to write your way out of this hole. Sometimes writing a blog is an opportunity to showcase one's own ignorance, and to learn something from the process.
It might be that in this circumstance the reader's only hope to gain something from the exercise is through happenstance. For example, it could be that you don't follow my reasoning as to why the following quote is important to blogging. It could also be that my reasoning is broken, in how it imagines the following quote to be of great relevance to blogging. None the less, here you are about the read this quote from Martin Schwarzschild. Perhaps you have not encountered it before. The original context was in discussions of stellar evolution (it's not the same guy as the eponymous radius associated with the spherically symmetric solution to the general relativistic field equations). I find it to be very much on point for almost any human endeavor:
"If simple perfect laws uniquely rule the Universe, should not pure thought be capable of uncovering this perfect set of laws without having to lean on the crutches of tediously assembled observations? True, the laws to be discovered may be perfect, but the human brain is not. Left on its own it is prone to stray, as many past examples sadly prove. In fact, we have missed few chances to err until new data freshly gleaned from nature set us right again for the next steps. Thus pillars rather than crutches are the observations on which we base our theories ."
