I had a similar experience using Blackboard for grad classes several years ago and really enjoyed reading the comments of others. I think sharing thoughts and ideas opens us up to greater experiences. I know it is often a huge step for some people, especially those who are such private individuals, but I think the rewards can lead to greater self-awareness.
Just knowing that others in my expanding circle of NHS friends have similar interests as me(gardening & reading!)makes me glad that I was lucky enough to land here!
