I downloaded Minecraft and downloaded 2 resource packs. When I went to the .minecraft folder, there was no \resourcepacks folder. Is this a bug, or because I'm running Windows 8, or what?
If you are using version before 1.8.1-pre1, game does not generate resourcepacks folder automatically so you have to manually make the folder. It is fixed in 1.8.1-pre1:
Fixed the resource pack folder not automatically being created when starting the game
