Since "redditor" is a community name, it makes sense there would be a different internal/employee demonym and Snoo fits the site as good as any other name might.
You're welcome to take the cynical approach to that, sure, but I've never felt it to be a particularly harmful thing. It's good to have some semblance of a friendly culture, if only to break up the day.
Some people will like it and I'm sure some people hate it. I've never given it a second thought though.
If others bond together from that, I get it now.
