Are blogs fair game for grammatical critics? Let me know!

I recently received an email from a gentleman who stumbled upon my blog.

"I have had the misfortune to accidentally come across your blog. As Director of Admissions at OBI your English is also quite awesomely dreadful. Does one have to be illiterate to be admitted to OBI?"

"Ed Always" edallways@hotmail.com 

Mr Always did not check out the back dated "issues" of my blog.  I held a discussion last year around this time about the need of blogs to be grammatically correct.  The consensus of the people who responded was, that as a representative of a college, I should make an effort to police my grammar, punctuation and spelling.  However, in the environment of a blog, as my friends pointed out, normal rules are relaxed.  I do not have to live up to the standards of Oxford, which I assure you, I do not, but I should make a try. 

I often return to my former posts and clean up mistakes I find or others point out.  I do not have my blog posts proof-read as I do my other school related correspondence.  Is this a mistake?

I started this blog as informal way for prospective students, current students, graduates, and the world in general, to get to know me and OBI.  Was this a mistake?  Olean Business Institute is a different kind of college than most people are used to.  We are very much student oriented and strive to make the kind of atmosphere people can thrive in. 

I did respond to Mr. Always and pointed out a few mistakes that he made in his short note, and in three sentences, there was a lot of them.  Can anybody point them out?  I also asked him to point out my errors and I would be sure to correct them.  As of now, I have not heard back from him. 

I also want to take the chance to assure my friend Edward, that the students at OBI are not illiterate.  I would think a job placement rate of 90% or higher would attest to that fact.  Our students are a hardworking group of people, who more often than not juggle families, jobs, and fulltime classes.  I would hate to be in his shoes if any of our non-traditional students who pull 4.0 averages ever come across Ed in a dark alley.  It is not cool to insult them.  I can take it and I am used to it, but to bash someone who puts more effort in one day than many (our detractor among them?) do in a lifetime, is extremely low.

What does everyone think of this issue?  Feel free to answer my questions and weigh in on this subject.  I look forward to a wide variety of opinions.  Maybe, we will hear back from Ed.  I would hate to make him a pariah.
