Here's my video of my project.

It was interesting to compare and contrast different aspects of open and closed PLCs. I think that buy in really does impact the effectiveness of PLCs.

I found a great graphic on Flickr by doing a search for "PLN PLE" which shows the relationship between PLEs and PLN. I appreciated seeing this relationship visually as I was not quite sure initially how the two related and were different one from another.
The other valuable point I gleaned from this graphic which helps me understand better how Personal Learning Networks function, is the point that there is a "sharing spirit" associated with PLNs. I find this to be one of my weaknesses in participating in Social Networks. I like to find communities, and lurk to find out the information I am looking for, but rarely do I contribute myself. I think this is mostly because I don't think I have very much that I can offer that is unique. I do think that sharing is important though.

How can I add an image to this post?
