Wiki Minutes?

While reading this post about wiki collaboration an idea popped up. I am secretary of a couple of meetings. This means I have to write minutes. These minutes are quite formal, written in a template, published with approval and distributed. But before they are distributed I regularly have to ask several meeting participants if I correctly jotted down their point.
Well, here's my idea. Wouldn't it be nice if everyone at the meeting had a Google Document of a wiki page in front of him/her? The secretary would have primary responsibility for the minutes. But all other can read along, change and extend the minutes. This makes things must nicer for the secretary and by reading along with the minutes the meeting will hopefully keep to the agenda (point).
Or is somebody already doing this? If so, what are your experiences? And if nobody is doing this, what do you think of this idea?
