"You can use Twitter as a megaphone to other places," Rosenberg says. "As long as you keep it around a central branding theme, you can help people get an idea of the types of things that interest you professionally."

As for the don'ts? Well, it might seem obvious (and the have been pretty well-documented at this point), but avoid bad mouthing previous (or current) employers, and watch for the tweets that, while perhaps honest, offer too much information.

"If you're looking for a job, don't tweet something you wouldn't want your mother to read," Rosenberg says. "If you're younger, don't talk about going out partying tonight or how you were partying so hard that you can't imagine getting through work. That's obviously not something a future employer would want to read."

Designing Your Twitter Profile and Integrating it Elsewhere

Be sure to use a good, recognizable head shot in your Twitter profile, says Schawbel. In terms of the profile information, you have to write a biography in 160 characters or less, so make it count and try to cram in a keyword that will be recognizable to others in your field (such as "business analyst" or "project manager").
