Once a surrealist, always a surrealist. If you have grapes to grow and give, it might change into something else, and this is what Food Swapping is All About.
I hope that the group (sadly not official yet) will be successful and large. Sweden needs more like this. But I imagine wider swaps; why not art swaps or work swaps or perhaps even swapping lives? And economy wants swapping dearly. It might change into something that actually looks like a market, tents and stalls and fruit stands and all. We might use money for swapping wares and services easier (this might even become the first reason to have a currency -- I beg your pardon for this unusually wild suggestion) -- that is, if we have to use money at all. Let's swap.
