Your bragging about taking misspellings and lousy grammar in your stride has to do with your tolerance for low-quality input.
I can read and understand my own writing just fine (unless I inadvertantly leave something out).
If somebody else wrote in my style, I would pick it right up. It appears to be a matter of matching the thinking and processing styles of readers. If the world was full of Tablizer clones, we would be tickled pink with my writing.
Again, it is hard to tell if the "proper" conventions are based on statistical pychological research, or the subjective opinions of dead pompus white guys from yonder. I have not found a reasable substitute for many of my usages of parenths. Should I toss them just to be "proper", or focus on readability as I percieve it?
