We get tips. Lots of them. Sometimes Gawker features editor Tom Scocca responds to them. These conversations are memorialized here in an occasional feature we call Tom Tips Back. In a special treat, today's correspondence was initiated by Tom himself, in a Tip directed at Toronto Star publisher John Cruickshank. Last week, after the vindication of Gawker's initial reporting on the existence of a video of Toronto Mayor Rob Ford smoking crack cocaine, Cruickshank wrote that the revelation was the result of "work of a scale and seriousness that can only be undertaken successfully by what is now called 'the mainstream media,'" and that unnamed "others lack the resources, the experience and the credibility to call a senior official to account."
