Two laundry baskets in the walk-in closet in our bedroom- one for whites, one for darks. My clothes go right into them when I take them off, or if they’re clean enough, get hung right back up. I hate doing double work- if I take it off and toss it somewhere, eventually I’ll just have to pick it up and do something with it. So I just do it in the first place. Plus, my wife works hard enough keeping the house tidy and ship-shape; the least I can do is put 0.5 seconds of effort into keeping my clothes off the floor/chair/bed/dresser/etc.
Hamper in the bathroom (because it’s large enough and my washer/dryer is in the mudroom, which is already cluttered with random stuff.) Also the bathroom is off the mudroom, so it works out.
Sometimes it spends a day in my bedroom, or wherever I end up disrobing.
It’s not a hamper exactly, but one of those three-bin sorters like this: http://ecx.images-amazon.com/images/I/31n0%2BxxxVKL.SL500_AA300.jpg only mine has wheels.
Depends on where I take it off. In my bedroom I have three hampers (whites, darks, dry cleaning) and I have another in the bathroom for stuff I take off in there. On laundry day I portion that out into the other hampers as appropriate.
I have a hamper in my bedroom that most things go into. Though some things go on the floor, like pants and shorts, things that I may wear again in a day or so. I used to just put things into piles on the floor, but I’ve gotten a lot better about that in the last year or so.
Yeah but it’s duct-taped together, so it’ll be fine for years to come! 
I’d also like to mention here that I have a laundry chute, which is much coveted by many here. However, I only use it for linens. If I threw my clothes down there they’d be mixed in with the linens, I wouldn’t know how big my pile of dirty clothes was getting and worst of all my underwear would be right there in the face of my basement-living roommate. Eeeew!
I put mine in a laundry bag that hangs off my closet door. Since my entire living space except for the bathroom is all one room, I don’t consider the closet in the bedroom.

Our hamper is tucked beside the washing machine in the kitchen. When I change I always take the dirty clothes to the hamper right away, but I know others in the house often leave them on the bathroom floor behind the door. It annoys the crap outta me.
I put mine in a hamper in the closet. My husband drops his clothes beside the bed every night. I grab them in the morning and put them in the hamper (I care more, so I do it). I dearly want one of those 3-space hampers so I can auto sort the laundry into lights/darks/dry cleaning. We just bought a house and funds are limited, but it’s on my wishlist!
I made it a New Year’s resolution about 10 years ago I would never go to bed with clean clothes in the laundry basket. I was tired of digging around looking for a matching sock or trying to futz with a wrinkled shirt at the last minute. I don’t really mind doing laundry and I love it now that I make sure the clean laundry is put away/hung up on laundry day!
Slob by nature. I have a spare bedroom and I usually throw dirty clothes on the bed in there. They’re out of sight and easy to gather up when it’s time to do laundry.
I am, alas, a total slob. On the floor.
Mine goes straight into the washing machine.
Skivvies in Australia are turtlenecks. Causes me no end communication errors. 
If I get undressed in the bathroom, they go in the hamper there. If I get undressed in the bedroom, they go on the hamper there. Once a week the one in the bedroom gets emptied down the stairs, the dirty clothes get picked up at the bottom of the stairs and put in the bathroom hamper, then separated into piles of like clothes and washed.
Another, smaller pile lives on top of my husband’s oak chest/box thingo. Those go to Laurence, our dry cleaner/launderer. These are suit pants and jackets, girl clothes like dresses and skirts, and (mostly, I have a couple) shirts to be washed and starched. Essentally, if it needs to be ironed, he gets it. I do not iron. We put them in the blue bag and then Laurence rocks up in his van and we make an exchage of money for clothes from last week, give him this week’s and off he goes. We love Laurence and we hope he never goes out of business and makes us find somebody else.
So that’s our system. Hamper, pile, blue bag.
Basement floor, by way of the laundry chute in the bathroom. Ideally it would end up in the hamper at the bottom of the chute but no matter how I position it, most of the clothes end up on the floor.
Not a slob, but mine go on the floor. They are only there while it’s dark because they either get reworn in the morning or taken to the laundry after I shower and dress.
I used to have a rigid system of laundry hampers.
Then I moved in with Asimovian.
In any case, dirty laundry goes into one of the many hampers. Clean laundry gets dumped on the bed so we can’t be lazy about hanging and folding it. I mostly do the washing and he mostly does the folding and putting away.
We have a laundry chute in the hallway which takes the clothes downstairs into a cupboard in the laundry. Makes the whole process very simple.
Dirty clothes go into either the laundry basket or the drycleaning/handwash pile in the linen closet in the hallway. I wouldn’t want to have a separate hamper in every bedroom. We have a 60 year old house - the bedrooms aren’t big enough to accommodate all that!
Agreed. My laundry is SUPPOSED to go in the hamper, but often ends up on top of the hamper or beside it, forgotten in my gym bag, on the bathroom floor, and in the washing machine where it sits until someone decides to turn it on. My partner is the same way. I cannot vote without multiple answers.
When I lived in China it was the housekeepers problem.
We are building a new house, and one of the pre-conditions of building a new house by ChinaWife is that there is a laundry tube from the 2nd floor down to the laundry room. We started the permitting process last week.
