You know, other than the point about age, I pretty much agree. I just think that it is not limited to only young people. Old people can be stupid and ignorant, too.
My only modification, since this is more than just a bodybuilding site, is to require a peformance shot for those of us who are not bodybuilders. For example, I powerlift and do strongman. I am not lean, so a pic of me posing would not add any credibility to my posts.
This is not to say people can't offer advice outside of their experiience, or what their body looks like they experienced. It just give some perspective to where the post is coming from.
These are just some thoughts. But without pictures, do I even have any credibility?
