Good posting is one of the important factors for blog success. In addition, posts that are easy to read will help visitors understand what they are writing.
Don't we write so that others know what we write?
I think, no matter how good the writing is, if it's not made in a good structure and effective language will be difficult for visitors to read.
Regarding the above, I think you are truly a true blogger, @artguru!
To answer your question: You be surprised how many people write stuff and think people will understand what they write. The fact is we know our subject so much, we forget not everyone understands the topic or it's jargon. And so it's hard for them to follow and understand.
