It's been quite some time since I last used Microsoft Word for any serious document. Nowadays I mostly use LaTeX. Which of the two is “better” is not a discussion I want to get into: each has its own pros and cons and is suitable for a different purpose.
For those who are for some reason stuck with Word, I've been wanting to write an article on “proper Word usage” which takes much of the pain of the program away. However, I just discovered that this article already exists (and how couldn't it?): Living with Microsoft Word: Tips for survival.
No Word user, frequent or occasional, should be without the knowledge in this article. Spread the word! — Erm… sorry.
