Actually…by NOT using Twitter, but the power tools that you can download and install for free in your browser.
Have you tried them?
You may start with the native Twitter.com interface, but after you get comfortable with it – there’s no reason for you to use that anymore.
Consider using smarter tools to support your social media and Twitter work.
And, you can use them on the road with portable devices too.
As always, tools are only part of the social media success equation. You must build out a strategy first, and structure your social media plan to match your audience requirements, including the market that you serve.
