Droplr — for shortening links and mostly for sharing quick screen grabs.
Dropbox — saves my life.
TextExpander — saves my fingers.
FastScripts — for quickly executing Applescripts.
Bluetooth — I like to keep in the bar so I know if I am connected to anything.
Battery — Icon only because all I need to know is that a red color in my menubar means I need to find power.
Keychain Access — Allows me to lock my screen when I walk away from my Mac, but I need to keep it ‘awake’.
WiFi — Yep.
Clock — I keep it on military with no weekdays so that I don’t waste too much space.
Spotlight — I would ideally like to rid this, but leave Spotlight active.
