Maybe they left because they had reached the end of a chapter in their life.No man or woman is bigger than GAG. If a "well known" user wants to leave let them go. People are here to offer and receive advice. No ones opinion is more valuable than the next person's. If one person leaves another person has signed up. There are better ways to "protest" than to leave and hope that someone will miss you.
Protest, some of them probably. I think a lot of people (myself included) are just running out of patience and interest for this site and all the people on it. I figure I'll at least have some fun and see how long that lasts before I get banned or just stop signing in lol
