Don't worry 'boston area dtv', it's a given that the general public makes (frequent) spelling and grammar errors. My point again is, when a website has mistakes like this, it looks bad for the site.
Admittedly I'm biased against poor "English" skills. I took various "English" classes throughout most of my 12 years of regular education plus classes in college. On the regular education side, I'm positive that students MUST take some number of years of classes in different subjects, i.e. "X" years of math, "Y" years of social studies, etc, etc.
