San Jose Mercury News columnist Dan Gillmor is one of the world's leading technology journalists - and after patrolling the silicon valley beat for the past decade, it's no surprise. He wrote extensively about the dotcom boom of the late 90s and had a front-row seat when the industry collapsed in 2000.
Now he's releasing a book, We The Media, which examines how grassroots journalists are challenging big media's dominant position in news coverage.
Dan will be taking some time out to join us for a webchat this Thursday, August 19 at 3pm GMT - and he's ready to answer your questions.
