Taking the time to use proper spelling and grammar makes anything you write or type significantly easier and more pleasant to read. It can also be seen as a sign one is taking it at least somewhat seriously, as they went through the effort to use proper grammar and punctuation.
It's not really necessary to point out but I do have to agree it IS a horrible blob of text that few people would take seriously. If you care enough to respond to us pointing it out you may want to consider fixing it up, else you can just ignore us as you'd consider our comments pointless.
