I try to use my full name or variations thereof because it forces me to maintain a level of civility and respect for others that is often lacking in the online world.
The forums I frequent that enforce a screen name policy of “full names only” tend to contain the most cogent, thoughtful posts online.
Nothing against my fellow Piggs, who are a pretty smart, well-read group of people. But I have seen some knock-down bare-knuckled flame brawls here.
IMHO we could all use a little more civility in our lives.
