We bought some tough plastic ones about ten years ago, and inherited a bunch of old (wooden) ones (spring-type) with our house, along with an old clothesline that we removed after a couple of years. Since then we've used a combination of the electric dryer and indoor lines in the basement (about half and half). Once in awhile a pin would snap, and we've lost a few here and there to craft projects.
This year Mr. Fixit put up a wonderful energy-saving pulley-style line outdoors; you can stand on the back porch and haul everything in if it rains. So I thought we needed a few extra clothespins. The new (wooden) ones are cheap enough--but they break! The springs on them barely hold a pair of socks, much less take on a pair of jeans.
I have to go down after each load and check the grass for broken clothespins. And/or pick up the things that have fallen off the line.
And that's how I know this world is going downhill in a laundry basket.
