RE: If You Habitually Have Typos In Your Work, Should People Listen To What You Have To Say?

I think grammar matters to people who have mastered it and understand that it's a system of logic, and it doesn't matter to people who haven't mastered it. Tonight, I was scrolling through after a long day of writing, and I didn't even open blogs that had obvious mistakes in the visible content.
The easier a piece is to read generally the longer it took to write, because the writer took the time to refine ideas, to check facts, to find the right words, to check spelling and catch homophones, to vary sentence structure, to watch for problems such as dangling modifiers or lack of parallelism. Why shouldn't I reward that writer with my time, my upvote, and my comments?I think your point about credibility is so important. If a contributor was too lazy to even check for basic errors, what else was that writer too lazy to do? I definitely judge a piece at least partly on the grammar, spelling, and punctuation, but like @telos, I make some--not a lot--of allowances if the ideas presented are inspiring or inspirational and coherent enough for me to extract them.
