There is a good reason for not posting one's full name on Internet forums. With Google and other Internet search engines, it is extremely easy for prospective employers or romantic partners to conduct their own background checks.

I'm not done with my career and if I should seek a new job either through choice or necessity, my comments posted in these forums could eliminate from consideration. It's even possible, they could get me in trouble with my current employer (I do not work for a railroad, but I am a transportation professional).

Likewise, a rail fan who is dating around may be rejected by potential romantic prospects for comments posted on a forum.

For those who are retired, self-employed, married or just don't care what others think, more power to you. But in this day and age, there are many of us who cannot be too careful.
