The Ruthless Guide is about anything interesting, important or intriguing that we can find experts and people with experience to talk about and that we can find an audience for. 

In particular, the idea is to talk about the more difficult experiences of trying to get something done and to find ways of getting over those difficulties, some of which may be a bit embarrassing to admit, but without a solution you might have to abandon the task. Also, to do it with a slightly sardonic sense of humour - if possible.
