Like any app, twitter has a learning curve, and after about six weeks of active use, I feel like I'm crossing the threshold of being comfortable. What have I learned about successful tweeting, aka, rules to twit by? Here goes:

• Personality rules; voice and tone trump URLS
• It's the (cyber virtual) watercooler--ask and ye shall be @ replied
• Little links are useful, but not if every post is twit-linking to your stuff (ugh)
• Twitter is beyond transparency, this is a medium where truly being expressive makes a huge difference
• Feel free to be opinionated, it's not your blog
• Twitter is the small footprint of the Net; if it was a car, it would be carbon neutral.
