Yes you can meet, but nothing replaces the experience of time with someone and the nuance of everyday life. I could surely learn a lot by the sharing of myself and them sharing with me online. But the benefit of time with someone physically in your life determines compatibility. A good start online, possibly, you will never know until regular contact is put in motion. Things and people are a mystery until face to face. You cannot predict temperament from an online tryst.
I think about myself. You adapt and change with time when you are with someone. You cannot predict these things online. I surely was open to my wife starting a career after college. When we decided to have children, I was able to comfortably support our household with my career. She, given the her own free will, was able to chose whether to begin a career or start a family. She chose to raise our children, and I have a lot of respect for that. So much so that I am keenly aware of what she sacrificed and do everything to emotionally support that. See she did not have to forgo a career but she did. This is life and issues that shape us as a family happen in real time. I hardly doubt that these can be vetted online. Online is probably a wonderful introduction to learn someone's moral and ethical values. All long as you are trying to actually find those moral and ethical values when talking to someone online and not just looking to look, or to satisfy some temporary craving for affection.
Introduction yes, would it keep me from meeting someone in real life, no way, because real life is the only way you are going to know a real person. Otherwise they are just words written somewhere.
