What I believe would be cool is that no ages would exist in profiles. I usually don't look because everyone is at a different maturity level and also experience level. To put an age would prejudice one when talking to another. If all were considered on a level playing field then I believe people would be taken for what they believe and their words more seriously instead of "this person is immature because they are only 15." There are many intelligent 15 year olds, just like there are many ignorant 30 year olds.
