I think moderators should keep to the job of moderating infringements of the forum rules. They should not be allowed to give their personal views or opinions in any way shape or form. That includes having signatures which advertise personal views or opinions.

Maybe they should have a 2nd standard member login/username for purposes of participating on a personal level.

On rare occasions, moderators have been known to use their staff powers to steer members opinions of certain distros/apps/scripts/beliefs etc.

This does not reflect well on a forum's image.
