No it's not a website for those looking for/phobic of cul-de-sacs of the flamboyant. And yes, it does have one of the dumbest taglines I have come across in a long time*. But this website is, in its undeniably loopy and Californian** way, kind of an awesome idea. Basically, if you have a fruit tree/blackberry bramble/zucchini infestation that is providing you with more produce than you need, you post it here and people will arrange to take some of the surplus off your hands. Conversely, if you live in a completely fantastic but undeniably third-floor apartment and would really like to have some Meyer lemons, you can visit the site (free to everyone while it's in beta, don't know how long that will be), find someone with a tree near your work, and go help yourself. Everybody wins!
(Especially me, because Cameron made Meyer lemon-poppyseed muffins for breakfast today. I like muffins.)
*My suggestion for a better one: "When life gives you way too many lemons, make a website to get other people to come and pick them."
