The topic title is "Biker Kid ..." Nowhere does it ask for comment and critique or just comment or anything else. Perhaps your original post did however.
If you are just sharing a photograph then share it and be content with the knowledge that you might have made someone smile. If you want comments about the photograph it's a good idea to let people know. I can't speak for everyone but I, personally, won't critique a photograph unless it's asked for and I normally won't comment on one unless it is a really outstanding shot or someone I am familiar with.
