I have conducted a study on how promoting your age helps you achieve readers as well as members. There have been many opininons but I think that I have finally come to a conclusion. The reason of my study was because there are many people who ramble about Carlocab being a scam just because he advertises his age everywhere he goes. You can find my study Here if you want to read it.
Age does sell - it seems to be a huge thing for people to read stuff written by a 14 year old as opposed to a 30 year old. I'm not sure why, but perhaps I should take this to my advantage (I'm 14). Sadly, I'm not a sellout. By the way, thanks for the mention in your post!
On the opposite edge of that, if the seller is younger, people may think he knows absolutely nothing about the industry.
The only real use I have for "young promoters" is either fresh perspective which is untainted and uninfluenced by the traditional views of society.. or...forcing my 10 year old cousin to try and browse my sites to make sure they pass the "so easy to use a 5 year old can do it" test. Most other determinations I make are based upon merit and knowledge. Everything else is useless to me.
