Now I must admit I'm not an English major, but 99.99% of the time all my work goes through a spell check before being published, to check for any potential problems. Even if you are an English major, grammatical mistakes will eventually slip by, and when you type at over 70 words per minute you're bound to hit a wrong key now and then. ( I know I do ) Its always a good idea to bookmark a good dictionary site or have one handy. It also helps if others proofread your work. It looks unprofessional when you have potential customers visiting your site, and all of a sudden they come across a spelling mistake. Now if you make mistakes on your site, who's to say you won't do that on a customer's site? Unfortunately, we are humans, and these things happen. I've had visitors email me a few times pointing out a few grammatical errors here and there.
