I love this idea and think it’s a great use of the web. On the Make: Talk episode with Erik and Kelly of Homegrown Evolution, we were talking about the fact that, frequently, too many people in a neighborhood have too many of the same vegetables in their garden (e.g. everybody has tomatoes and basil). This is a great way to coordinate and distribute your bounty, in this case, the fruit that grows in your yard. For instance, I have really good Concord grapes, more than we can eat. I might try and trade for some other fruit.
