*********
Notes: Some of this stuff appears to be really old or outdated. I tried USBOverdrive for a day, then deleted it. I installed (and paid for) Screenflick, but then I never used it. Same goes for Glims, which appears to be a Safari plugin - I only use Firefox. I have no idea what ProTec6b is.
The only apps that have updated recently (that I'm aware of) are BetterTouchTool and Java. Both of these have updated in the last few days.
I have Gatekeeper set to "Anywhere" because I download certain apps from the developer's website (instead of the Mac App Store).
