Response to third opinion request:Hi, I'm here to give your third opinion.  I think it's important to keep in mind that this article is titled "Common English usage misconceptions".  It's not "Common English mistakes according to professional typography standards".  It is clear - to me at least - that the hypen is often misused.  There's no dash key on my keyboard.  I know how to make a dash, however, —.  But I do web dev and work for a printing company. And I just started a sentence with "but", and this one with "and".  I know all these things are wrong - but they are convenient - and I'm writing this somewhat humorous third opinion for a few guys on an article talk page.  So, in my mind, the question is whether this is a misconception, or just ignorance.  I believe that to properly call something a misconception, it must be believed to be a rule, when in fact such a rule is not correct.  I've never heard anyone say, "just use hyphens for everything".  It has only become the default, because we have no dash keys.  So I would lean toward excluding this entry, unless you want to change the scope of the list to include all common mistakes, not just misconceptions.  Hope this helps.
