From my experience, meeting minutes is very important for different reasons, firstly, it summarizes all that was discuss in the meeting for a record and reminder as well. Secondly, It defines the action item and ownership of the action items after the meeting. As we learned every Pm has his/her personality and style, but it is very common that you will find these two points in meeting minutes. I find them very helpful too especially when you are working on couple project at the same time and you had more than one meeting regards different project in the same day. It is always good to recap on the topics was discussed on the previous meeting and tight it to the notes you have. Personally, I find it very important and I start to write my own meeting minutes if I know the host don’t send one after the meeting.
