I see myself in front of a virtual word... which is still very empty. Frankly, a plane and a few boxes. I want to put some placeholders in there.
I know that I am not an artist, and I am lacking the necessary skills for some of those things I need. Also, I want to try out stuff quickly, without making assets which I will throw away anyway because I decided against a specific feature. Then, I want to show the whole thing to people who can create the necessary assets for me.
I am pretty sure that most (if not all) game developers hacking around have that very same problem. So what do you use in place of your final resources, and where do you get your placeholders from? Simple meshes, textures, sounds, etc, maybe not even high-quality, just so that you can put something there....
I would use semi-shiny grey cuboids. Not sure about sounds; maybe some goofy assortment, but timed appropriately for whatever event the sound is playing for. Perhaps that would generate ideas later.
I will use 'lorem ipsum' text for dummy content, I've created 2 user avatar images I use (one light and one dark) for dummy user images, plus an image of a nebula I use any time I need a dummy background image. (These are for mockups and prototypes, not for skeleton content an end user would ever see in production!)

I played a little with Amazon's Lumberyard, and it has a marketplace with many free assets (plus the support of CryEngine's market assets).
Or you create your placeholders but store in a repository instead of a trash bin ;-)
