Okay... so I heard good things about using the "RAW" image type on my camera to better be able to play with the pictures and such. So I figured I'd try it out! Well... I was going through my photos cuz I wanted to post them today and start sorting through them! Well... turns out I'm REALLY smart cuz you need a special program or codec to be able to work with that file type. So... pardon the delays while I figure out how to deal with this .NEF file type! =P

Also most camera sensors are a mosaic like this:
[color=red]████[/color]
█[color=blue]███[/color]
[color=red]████[/color]
█[color=blue]███[/color]
So instead of storing the 'blurred back together' single panels of R, G, and B, it stores the raw mosaic in that case as well for handling scaling better.
As for software, I STILL managed to forget to link to this, it's probably the best tool out there for every platform under the sun:
RAW Therapee
Also, RAW data images contain no compression and minimal data handling from the camera. Its basically a digital negative and has benefits for high quality production. For general users like you and I who are taking photos to share with friends therea isnt any real reason to use it. If you wanted to take a sunrise picture of yourself in your suit sitting on a beach for use in a frame or artistic situation than using a RAW format is would render better quality. But if your just going to change a RAW data file into a compressed jpg to share on the web than the benefit is moot.
Luff ^_^
And I'd disagree on being useless for hobbyist level folks: It lets you "just shoot" and deal with many adjustments after the fact at your leisure, instead of caring as much about getting all the settings right (sunlight/indoor lighting/fluorescent lighting) so for convention photographs that aren't entirely indoors it can make things easier to get good quality photos out of it.
KEEPING the RAWs once you've made the set of JPEGs you want to show off and keep? That's something useless to most hobbyists, but working from them removes the time constraints while shooting of adjusting the camera all the time. =^.^=
And I only say 10% because thats the maximum amount of effort I'd put into any single RAW image in a reel XP
If you enjoy spiffying up pictures and making them as good as they can get than on or off the camera you're probably above a 'hobbyist' level photographer =D
If you're truly of a 'point and shoot' stance, that's back at amateur/tourist photography, and then yeah, RAW is pointless and even most modern top-end cell-phones can take excellent photography at this point for that use case. =^.^=
Your terminology may differ, that's just my breakpoint.
