I am still uninterested and impressed with people who can't use a real name / picture on a forum. I take very little of what they say into consideration and just figure that they are hiding from something for some reason. A company name / logo is fine, but to totally hide from the community just seems weird to me. If I walked into social event and 1/2 of the people had paper bags over their heads and no name tags, I know who I would be talking to and who would be ignored. Profile pics are a good idea... avatars were childish and unprofessional and a person sure as heck doesn't need 2 pictures.
Not everyone wants to, and not everyone can. If you want everyone to know your name and see your picture, you can stick with Facebook. Post your real name on a forum and your picture and you'll eventually find it popping up in search engines for years to come. I don't walk about on the street with a name tag on my t-shirt, I give my name out to people who need to know. I don't think people need to see my face on here, nor know my name as I'm only on here for support reasons etc. Also, let's say someone runs a military forum for ex and currently serving soldiers to meet online to share news etc. It wouldn't be the wisest thing to have their real names and photos splashed all over the site. But as you take very little of what people say (without a real name or picture), I don't suppose what I'm saying is of any importance. Also, if avatars are childish and unprofessional, then I suppose everyone in this thread other than you, is childish and unprofessional, as it seems it's only you that's using a picture of yourself, that is indeed if that's really you (as people can always lie about their identity anyway).
What I'm trying to say, is we should be given the option, not told what to do.
