Before I do the "reveal" on Monday and talk about how to use Twitter for Business, I feel it's very important to hear what others have to say on the subject. This post contains a list of leading voices.

I'd like to ask you to do a little homework over the weekend and review these. While there won't be a "pop quiz" on Monday, it will get you primed and ready for the final post in the series.

(BTW, here are Parts un, deux and trois)

Active Rain Twitter Group - Did you know AR had a Twitter group? They do and it's great. In fact, it's probably one of the hottest groups going right now. There are scores of others talking about this subject here and I bet you could find answers to just about any question you have on the subject. In your quest for Twitter mastery, start there.

Kim Woods Twitter Series - One of our very own here at AR, Kim Wood, is doing a series of her very own. It's better than mine and I'd take it personally if you didn't read it.

Why Your Company Needs to Be on Twitter - This is a survey conducted by social media strategist Warren Sukernek (I know. I love saying his last name too. :->) and Peter Sorgenfrei. It is one of the best posts on the topic of using Twitter for business that I've seen. If you don't read anything else I've listed in this post, read this!

It's posted in a great (GREAT!) online community called The SWOM (which stands for The Society of Word of Mouth) that I'd love to invite you to join. It's open to anyone.

Making a Business Case for Twitter - Connie Bensen, online community consultant and my friend, has compiled a list of reasons businesses should consider using Twitter. It's excellent. Even better is her post, Twitter 101, which contains links to a number of other resources.

Twitter Handbook - Another of my friend is Deborah Micek, known as Coach Deb on Twitter. She's not only written a book on the subject of using Twitter for business called Twitter Revolution, but has this blog, Twitter Handbook, as well.

Speaking of books, I did a search on Amazon using the keyword "Twitter," and here are the returns. It's amazing what is already in print about the topic considering the length of time its been around.

Twitter Business List - Laura Fitton, known as Pistachio on Twitter, has compiled a reading list on the topic. She is also authoring Twitter For Dummies, set for publication sometime next year.

50 Ways to Use Twitter for Business - From my friend Chris Brogan.

The Evolution of Brands on Twitter - Jeremiah Owyang, Forrester analyst and all-around schmart guy.

Business Uses for Twitter - If Valeria Maltoni says it, you know it has to be good.

Building a Twitter Following - What's your strategy for finding Twitter followers? In this post Jeff Tippett outlines an approach for building a Twitter follower base that's good for business.

Ten Ways to Market Your Blog on Twitter Without Being a Spammer - We all want to let people know about our blog, Web site, etc. However, we don't want to be accused of being a "Twammer." In this post marketing consultant Jennifer Slegg talks about the right way (and the wrong way) to go about it.

And you can't mention what others are saying without referencing Common Craft's Twitter in Plain English video...

You probably know of a number of resources I've left off the table here. Please feel free to include yours in a comment.

Monday is the last post in this series. It's where I talk about how to use Twitter for business. Stay tuned!
