I am not sure of the impact of my contributions. My comments are made based upon my thoughts while reading others blogs. On some occasion I ask questions on others I agree because they have made points that I simply agree with. I do think there is a large impact on any career field when you have a lot of interaction. Social media has increased this interaction so I believe that we can have a great impact on each others learning if we choose to participate. If I choose to participate and reflect on others comments then the impact on my learning is greater. I also think that reflections are better for learning than restating what you read. I find that I get more out of those blogs that are reflections and not restatements. Those are the blogs that I tend to interact with more.
