Because I spend so much time on Facebook, twitter, etc., I see a lot of photos...a lot. And way too many bad pictures. I think if you are a professional photographer and you post a photo, you are saying you think this is good. Even if it’s meant for your family, it’s being shown to the public. When I see it, and it’s bad, I'm thinking you are not as good a photographer as I thought, hmmm. That’s what you are telling me. You never know who is looking at your post. Furthermore, when you post a bunch of photos from a particular event, some good and some bad, you are telling me you don’t know the difference between the good pix and the bad. So be mindful of posting pictures.
