Ever notice how the folks who are the most prone to lob an insult or accusation over the fence are also those who hide behind a closely guarded psudonym while online? And, the majority of their barbs are aimed at those of us who are comfortable enough to be here as ourselves, using our real names.
I know that there are many folks who use psudonyms to protect their identity from those within the organization whould would rat them out to the Brooklyn Feds, but many others just like to hide behind a facade and shoot their slings and arrows from far offstage.
When folks like Alan, Kent, Randy, Joel, and Englishman (along with many others) have something to say, they back it up by having the balls to say it as themselves. Such is not the case for many others, whose nom d'keyboard serves to hide them from any accountability.
