I was wondering why more users don't fill this out.
Can't see why not.Not necessarily a head shot. Maybe just a simple 250x250 image. It could be anything. This way we at least get an idea on what the user likes. And maybe show their name, age and gender below their username. This way we don't have to click on the person's profile, hoping we'd find more information.
Actually, I like not knowing those facts. When I was younger, I felt that my opinions were dismissed because of my age.Now that I'm older, I feel that sometimes my opinions which are flat out wrong are considered more valid cause an older person must have learned something in all those years!A 17 year old who is a serious student with a good teacher living in North Dakota, may have more to teach me about becoming a better musician than a 45 year old living in Paris who just has a lot of opinions.
