I had 53.13 GBs earlier, and when I opened up my Air a few minutes ago, I'm sitting at 52.75. I haven't downloaded anything or really messed with anything at all. Why are GBs disappearing?

That's actually just .38GB. My guess would be that it is RAM swap space or the hibernation RAM image.

Safari's webpage previews also takes up a lot of room with only a moderate amount of surfing.

When the RAM runs out of space, it starts reading/writing to the hard disk. Check your memory usage and close down the memory hogging programs.

I know Safari sucks up RAM like a vacuum. Lots of tabs open in Chrome will also chomp down on the memory. I have to close Firefox every few hours to push the RAM down, also.

Just some things to keep in mind.

Yep just restart your computer and you will see the memory return again.

I shut it down and the space comes back, but it doesn't make sense to me. I'm not running any RAM intensive apps, only using a GB at max.

When you close the lid, the air "goes to sleep". When that happens, the computer will transfer some or all of the active memory to the HD. That information is not just "deleted" upon awakening, some of it will stay there so as not to have to over think subsequent "sleeps".
