I agree with mooregreg49 that we are all aliases; TER handles are aliases.

I believe aliases provide many benefits besides the obvious ones. For one thing, it levels the playing field. At one time when I was one of the top posters, I had to submit a post to voice strong disagreement with a member who seldom participated and had very few reviews. I used an alias. He shot back at me emphatically, with unjustifiably  crude language. I was glad he did that. I wonder if he would have done that had I not use an alias.

We should judge the validity of a post by its content. It shouldn't matter if it's done by a new member, an old-timer, an alias, or not-an-alias.

As for other benefits. When I think of more, I'll post them in other threads with other aliases.
