As Apple's built-in Firewall preferences improves in both functionality and security, I will be aiming Flying Buttress more at users who need the advanced firewall configuration, logging, and IP sharing options found in Flying Buttress. There is no reason that a new or inexperienced user cannot use Flying Buttress, but Apple's own Firewall preferences will likely remain a simpler interface for configuring a basic firewall.
