Well anytime I can be corrected it's an empowering moment for me to take that knowledge and grow a little. I'm fairly educated, and still the least educated in my family, so being the "black sheep/dumb one" I have tried hard to better myself and live up to the level my family has carved out. Being erudite is not a bad thing
How one comes off looking is very important! This was something I stressed greatly to my wife when we first met, who had grammar/punctuation/spelling skills that were lacking. I used to drive her nuts, but today she really sees how people with less understanding of the language and how it works can be detrimental not only in everyday life but especially in business as well.
To use the excuse "well it's just a guitar forum and it doesn't matter", shows where and how one wants to be viewed in life. If you want to be in the dark, be in the dark alone, when you come out in the light to converse with others in the sunlit world have a modicum of respect for those of us who choose to sift through your poorly written drivel!!
Some of you have good, strong, healthy minds, why you would want to have less knowledge, or come off looking that way with an "I don't care attitude is beyond me. When I correct someone it's usually when they blunder on a grand scale. Not the odd forgetful moment. However, for my part, I am sorry for pointing out mistakes that will ultimately make you a more positively viewed individual...
