With Twitter all over CNN, bubbling up in the news and welcoming an influx of new users and companies, it’s time to round up great beginner’s guides.

UPDATE: We liked this 101 Twitter Resources from Traffikd 10.06.08

How to: Possibly my favorite is Tony Hsieh’s Beginners Quick Start Guide and Tutorial to using Twitter. Tony is @Zappos on Twitter, and the CEO of www.Zappos.com.

Caroline Middlebrook wrote The Big Juicy Twitter Guide

And Jennifer Laycock’s series From Twits to Tweeple, Why I Embraced Twitter and You Should Too is very helpful. She writes:

• part one where I gave step by step directions on getting your Twitter account up and running,
• part two where I explain how to send messages and take advantage of the Twitter follow/followers system and
• part three, where I explained how Twitter can help you meet new people.
• In part four, I looked at the traffic potential of Twitter and explained the value of retweets in making a link go viral.

Shel Israel put together 7 tips for new users, and Ellen Petry Leanse blogged her top 10 tips. Why to: Many have said these posts were useful “Whys” for Twitter:

• Shel Israel post about my personal Twitter story
• Twitter is My Village
• Twitter Makes Us More
• Ode to Twitter

Twitter in Plain English by Lee LeFever and his team at Common Craft looks at a good beginner “use case” for Twitter. Really, there could be 25 different versions of this video, but you have to start somewhere.

Part Five of Jennifer Laycock’s series also makes a great case for the whys. As with most questions, I asked my Twitter community what guides they like:

My friend @GoldieKatsu created this 20-minute tutorial that covers setup through more advanced uses. And here are some other sources: Tom Humbarger’s Do You Twitter? Twutorials is a blog of short video tips. @dhollings Twittin Secrets has a funny video, but I’m confused why it’s set up to drive traffic to so many different places. That might be something I’m less clever about.
