I'm not really feeling well enough for a full blown update tonight, but I'd feel lazy if I didn't post -something- so how about this?
SteamGifts is a site where generous people put up copies of games on Steam which you can then enter giveaways to win. It costs you nothing, and you automatically generate points to enter more giveaways over time (I think each time someone puts up a new game to win, the value of that game is somehow used to calculate how many points each user gets, so when there's a huge Steam sale or Humble Bundle you'll often get waaay more points to spend than usual).
I've won a good chunk of my Steam library off of the site and can vouch for it being legit. The only stipulation is that your Steam account needs to be a certain amount of days old, and needs to already have a certain number of games to join. This is to prevent people making tons of accounts to just spam the giveaways. You can join SteamGifts over here: http://www.steamgifts.com
