More and more publishing industry professionals are hanging out on Twitter these days, taking part in spirited discussions about what's going on in the book world. Even GalleyCat co-editors Jason Boog and Ron Hogan are issuing 140-character bulletins on a regular basis. All that open conversation creates tremendous opportunities for journalists—and, next week, mediabistro.com is sponsoring a panel discussion in which NPR's Andy Carvin, Shirley Brady of BusinessWeek.com, and NYU journalism professor Jay Rosen will tease out the possibilities. Their 90-minute session will cover the skill sets 21st-century journalists are scrambling to add to their arsenals, the digital tools they'll need to get the job done, and some strategies for "personal branding," which sounds an awful lot like what folks used to call "making a name for yourself."
