If this hasn’t happened to you yet, it’s only a matter of time: You propose an idea based on years of experience, but your client isn’t convinced and wants to think about it.

Microsoft Word is a good (if overly-complicated) word processor. And as I demonstrate here, it can sometimes even substitute for a professional design tool if you know a few tricks. But it should never, EVER be used for web design.
If you want to make a web designer cry, tell him/her that you built a website using Word’s Save as HTML feature.
