I dunno about that. If went thru everything I had took those things I didn't use in the last six months credo, I would have some perfectly good things left over. Camera lenses and other, camping equip, tools, non-seasonal clothes, etc.

I don't tend to keep useless things around as it is. I imagine there are quite a few people like that. I imagine at least in some strata of tech workers, who are into the latest and greatest, there are quite a few who'd have pretty decent things to recycle.

I've worked with people who just have too much disposable income as either singles or DINKs and buy/consume "accordingly."
