Its a blog post not a letter. Again, for you to think this must be formal English or subject to evaluation reflects some lack of reality on your part. I am stunned to encounter trolls on such a well-intended website. Appalling that someone would "judge" someone else's blog post on grammar, even when that blog post is quite good compared to the millions posted everyday.

i seen all kinda misteks in blogz*&%(! why dont you get busy with your real job Martin H and stop trolling. NO ONE has asked you to evaluate their work based on grammar or usage, so perhaps it is not very welcome. NO ONE has asked you to judge the authenticity of someone's writing on here, by which to make a determination of ethnicity or national origin. In some circles of the law, not that far away, such a practice is considered racial discrimination. You even assumed that Jeff was a female, which would be gender discrimination. if in fact your grammar and usage were excellent, i would bring some alarm to your lack of real world knowledge about the law related to discrimination practices. i guess you are just too busy on here to care or take the time to read about that!! so busy because people need you so much on here and ask for you to help them. hmmmm. nope.

its a blog post, and he does not have to meet your expectations. nor does bad grammar or minor errors in usage reflect immediately some imposter is at work. lastly, no one asked you to be checking to see if each contributor is actually whom they say they are, or of the race we assume them to be. you have overstepped your proper role for a website such as this. its a blog post not a letter, nor an academic assignment, let alone, a nationality or race test. whew. you are out a line!! perhaps a major ego! get a real life, and purpose. perhaps I should say, get a real job and get busy Martin!!
