This is an interesting topic that I have been struggling to get my head around properly lately. As somebody who is on a blogging crusade, I love it when people comment on my blogs but I rarely write anything in reply back to them. My thoughts are that this is a very inequitable system. A reader has taken the time to leave a comment and I feel that if I don't give them the time to respond to their comment, I am actually undervaluing there contribution to my learning. I have blogged about this before but still I continue to struggle with it. The more I think about it, the angrier I get with myself. It is actually very disrespectful to not even take the time to thank a person who has left a comment with an acknowledgement of thanks or a response. By responding to a comment, we can continue to add value to the post and a possibility of discussion could continue on and thoughts / ideas could be fostered.
Am I totally off base with this? Would love to hear your thoughts and I promise to respond!
