Blogging for beginners

Mark Berthelemy recently ran a workshop for our wider team at work, introducing them to the concept of blogging. I was unable to attend on the day, since it clashed with a lecture for my Masters' course. However, technology being what it is, I have been able to attend the workshop this morning.

Have you been trying to sell the idea of blogging to colleagues, friends, relatives? Or are you a newbie, still trying to get your own head around the concept of what blogging is and isn't. Mark's workshop is pitched at a very accessible level.
