Next week @DunkinDonuts and @WholeFoods will join @FlashlightWorthyBooks for an all-day workshop about the mysterious, rapidly-expanding world of Twitter--and now, GalleyCat readers can get a $100 discount on the workshop.

O'Reilly Media will give readers $100 off the admission price for Twitter Bootcamp on Monday, June 15, 2009. Just enter the discount code: "GALLEY" at checkout. GalleyCat will be there, reporting on the bits of 140-character wisdom.

As GalleyCat editor Ron Hogan reported last month: "Tim O'Reilly and Sarah Milstein will be presenting their wisdom to a live audience in Manhattan, at "Twitter Boot Camp." (Disclosure: mediabistro.com founder Laurel Touby is one of the scheduled presenters, and we're looking forward to covering the event for GalleyCat.) 'We're thinking about this as a training day,' Milstein told us, full of 'useful, actionable information' that should be of interest to corporate marketers, celebrities, authors, and any other public figures and institutions who want to stand out from the millions of other tweeters in the system."
