Spelling and grammar are “relatively” important to me, and I have found many a mistake on all sorts of websites. I would have thought, though, that a large company such as Apple would double-check everything going out their doors. Apparently not.
Here is a screenshot of the default webpage you from their operating system, OS X, get when you enable web sharing.
The third paragraph should begin “You’re done”, not “Your done”. For an explanation, visit wikiHow. For some reason this is a popular error, although to catch the error all you have to do is expand the contraction in “you’re” to “you are”, and the choice becomes simple. A related example is the difference between “it’s” and “its” (see this article for info).
Oh, and if you find spelling mistakes or grammatical obscenities on this website, you can always quickly let me know. I probably won’t change the offending article since a new RSS item would be published, but I’ll keep your comment in mind when I’m writing my next article!
