Think about it this way - your computer works fine offline without internet connectivity, so denying access to system utilities isn't going to do any real damage. Using little snitch to "Deny All except Safari Outbound" is exactly the same as working offline, except that your web browser now works. No Networks/Sysadmin/OS X experience required. By and large, the largest and most annoying culprits on my systems are the OS X system utilities doing background updates, syncing photos, etc.... Ironically, they are the ones I most want to shut down when I'm not on home WiFi. Plus, if you have 15-30 minutes one afternoon, it's a great way to get insight into what your system is doing, and gain some (small) amount of comfort that you know what's going in/out of your system. Well, that is, everything that isn't bypassing the kernel in the first place.... :-(
