3. Be Personal (to a point)

While you should heed the advice of the aforementioned section, you also shouldn't be afraid to be personal in your Twitter account.

For individuals, Twitter can be a very personal medium, and that's not a bad thing for business people.

Twitter can humanize you in the eyes of your followers (who might want to do business with you in the future as a result of that human interaction).

"Work relationships have always been infused with someone aspects of the personal, and Twitter is no different," Fitton says. "If you walked around the office and talked to people sitting in the cubes, people have different personality styles and quirks."
