#9 Wiki! Wiki!

Despite my inital snarky reservations - I find myself referring more and more to Wikis for quick answers to burning questions. However - like Paul Gilster says - use with caution. The ease of the edit function kind of scares me - but is really cool if you want to add your own 2 cents worth. It's a good starting point for students and many of the articles have good foot notes, links, etc. I found a really cool trains glossary that I shall forward on to my "foamer" husband - look that up in your Wikipedia!
