Yes, I definitely could have. But I don't know C#, so that would have been an awful blog post. :D

Indeed, this article would read just as well after applying s/\bgo\b/C#/ig, or should I say:

    Regex.Replace(articleText, @"\bgo\b", "C#", RegexOptions.IgnoreCase);

Or indeed most general purpose languages, which the article itself mentions.
