An open discussion can bring out many good things. Herb is OK though. It is right to question everything. Even the forum process. Questions are the things that spur research.
We all have ideas. Some good, some not so good. It is by putting forth the ideas that we see if they can stand and walk on their own (like children). We can openly debate ideas and techniques. We must not debate people. If some one is out of line, that should be handled one-on-one and off line. I don't see anyone out of line here.
Outside phycists and cosmologists we IT folk have just about the most free and open discussions of any group that I have been part of.
