I think it is appropreat to put a picture of yourself on your blog when you are aready and comforatble with the people out there are you really comfident that you can trust people. If you put a picture of yourself on your blog you have to understand that this is going to the whole world eveyone that goes on your blog and to be confident that you can trust people with your picture of yourself on your blog. Also for instance facebook i teust faceboook with pictures of me because people can only see thme if you are friends with them. I do not trust myslef with pictures of me on this blog because it is not blocked. I think that having a picture of flowers and sunsets is a better thing for me.
