There's a certain blindness in the other flaws I mention. Laziness seems an inadequate, and rather self-serving, explanation. "It's because I work so hard that my grammar is polished." Well, it might just be easier for you, because your brain latches onto details and is hardwired for rules. That my brain deprioritizes the cosmetics of prose for other factors, doesn't make me lazy, it makes me different. I still don't think that grammar or cosmetics in general matter all that much in actual communication of ideas--though it certainly can some times. And it is out of social graciousness that I make an effort to write with polish, not that I actually think it's so important. For instance there's this paragraph: "Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteers be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe." I would suggest lee-way in allowing others to show their deftness where they are most strong suited--and see our priorities as just our own singular set of priorities (perhaps shared culturally, academically, etc., but still likely our own), and not a some biblical standard with which everyone should abide.
