On the other hand, careless writing shows that the author places little value on his thoughts, for if he thought them important he would spend a little more time on their delivery, ensuring the contents don't get destroyed in the process.

I believe the truth is as follows:

You infer from careless writing that the author places little value on his thoughts, because if you were writing them and you thought them important, you would spend a little more time on their delivery.

[Corvus]

Indeed that is true, but it is also true that if you are writing things for other people to read, then what value those other people put on your delivery is more important than what value you put on your delivery.

If you are writing only for yourself, then things like grammar and spelling are less important because, presumably, you know what you meant. However, if you want other people to value what you write, grammar and spelling become very important.

First, because poor grammar and spelling sabotage your meaning and delivery. There were several sentences in the article where I had to stop and think "err... what is he trying to say?" It is entirely likely I misinterpreted the meaning of some of these sentences. The fact that the author understood and valued those sentences is of utterly no help to me.

Second, there are people who believe confusing and ungrammatical writing are symptoms of confused and unknowledgeable writers. I understand you may not agree with this but, again, if you are writing for other people then it is the other person's impressions you must consider, not your own.

Defending ungrammatical writing by challenging a reader's inferences and thoughts is not convincing because, if you are writing for other readers, it is precisely those inferences and thoughts you should be addressing.
