I think in spoken English this is the case. However, using the more formal "one" in writing, even on a blog, is a good way to clear up any misunderstanding a reader might have. Though the use of "you" is more and more accepted in everyday situations, clearly the use of "you" instead of "one" caused some readers of this post some problems. In writing, one should try to be as clear as possible to get one's point across to the widest variety of readers, unless one is trying to obfuscate one's point on purpose.
