I have had comments from a few of my higher users that they prefer to be able to answer anonymously because they don't want to appear to be showing off by answering to many questions under their username. That is one of the reasons I have left the option of answering anonymously. I would say the majority of the questions and answers are fairly high quality. Again, when you are dealing with user generated content there is no guarantees. I try to catch what I can. Thank you both for your comments. They are very helpful.
