I thought I would spread a little holiday cheer to the SP computer system and free up a little disk space. I'd be embarassed to admit the number of old versions of my submittals (albums, articles, trip reports, etc) that were still residing on the system. As hard as I try to do as much prework as possible before starting on a new submittal I always end up with many many corrections - moving pictures, aligning text, etc. Hopefully everyone is really good about cleaning up these old versions, but if you're like me, you might want to check the Page History on your submittals. You might be amazed (just don't delete the most recent version.)
I also deleted about 10% of my photos in the past few months - lots of photos I'm sure I thought it was a good idea at the time to upload, but were just sitting in la la land not attached to anything, never to be used or probably seen again.
