Why would you want to buy worms to compost them? Wouldn't it be better to compost your yard and kitchen scraps??

We have a large compost pile at the bottom of our hill in the back woods. It really doesn't get used a lot. Just added to. Bunnies are generally good at producing lots of good stuff to compost. We used to use a metal container (with a charcoal filter) for kitchen scraps - but all it did was get moldy and gross if we didn't get it outside often enough. And DH and I just never seem to get to the bottom of the hill frequently enough with stuff to make it worthwile. Anyone want to buy it? I got loads of extra filters, too!
I saw a compost tumbler at the local food co-op. Kind of like this...only different. Something like this might be good for folks without much space, without a lot to compost, and with critter issues....
