So, a new version of this image, then...
I second this recommendation. Whilst it's pretty much overkill for a single firewall, once you start looking after a bunch of them the management centre really shines. You need to invest a bit of work in setting up your components (hosts, networks, non-standard services, groups, etc), but then the drag-and-drop firewall rules and VPN's are a breeze, and templating and shared/inherited rulesets can save a lot of duplicated effort. Centralised logging can be a real time-saver if you've got traffic that's passing through multiple firewalls and need to track exactly which rule on one of them is blocking it...
I don't remember anything about Lost originally having a planned length, but in any case the last three seasons are 16 episodes as opposed to 24, so it's really two seasons' worth of episodes stretched over two years.
The last is a nice idea, but way to open to abuse:
1) Hire someone to spamvertise your competitor's website
2) Wait for the lawsuits against them to roll in
