I don't know anything about the science, I'll be the first one to admit it. But I am a punctuation, spelling and grammar freak, and I really have to agree.
It takes very little time to have someone proofread and I would be glad to volunteer if I am here when it needs to be done.
It is hard because of our cognitive problems, I usually have to go over everything I write several times to catch my mistakes. But the fact remains that in any field, in any conversation, if you want to be taken seriously and be seen as professional, impeccable writing is a must.
Again, I cannot speak to the science, and I don't intend to, but the spelling/punctuation issue is one that isn't debatable if we want to be taken seriously. If Gerwyn has a good point, then it detracts from it greatly in the eyes of others reading it.
I really think everyone needs to take a step back here in terms of reaction, I've been avoiding all these threads like the plague and I would imagine a lot of other members are as well. There's a lot of vitriol, and I know you guys are smart and capable of more civil communication. All the anger makes it not worth reading, especially with limited brain and energy. I won't be back to discuss this, but do extend my proofreading offer.
