This is commonplace where I live in Vermont, to the point where sometimes things are taken which you didn't mean to give away. You put "free" on it -- or don't, see above -- put it by the curb, and it's gone within the hour.

There are also plentiful thrift stores which take donations. The profound selfishness of throwing this stuff out rather than passing it on so eventually some person with less can have a better life -- the thrift stores generally are non-profits supporting the homeless, hospices, and so forth -- boggles my mind.
