Not sure why this is being downvoted. It's a helpful comment. I know I'd rather be corrected once than continue spelling it incorrectly.
Reading the blog I cringed every time I read 'to' and I'm sure I'm not the only one. It was distracting and hurt the author's credibility when he was telling the story about his attempts to 'improve the company emails'.
To me it's a big red flag when someone hasn't been able to pick up the correct usage of to/too in 20+ years(assuming they were educated in an english speaking country).
And then != than in his post as well. I think it struck me particularly because it was in the same paragraph that he was discussing his unaccepted correction of the corporate copy :/. Proper spelling and grammar are important even in casual writing.
