Craigslist, Montaigne-style

Montaigne's dad points out the need for Craigslist several centuries before it finally came around:

My late father, a man that had no other advantages than experience and his own natural parts, was nevertheless of a very clear judgment, formerly told me that he once had thoughts of endeavouring to introduce this practice; that there might be in every city a certain place assigned to which such as stood in need of anything might repair, and have their business entered by an officer appointed for that purpose. As for example: I want a chapman to buy my pearls; I want one that has pearls to sell; such a one wants company to go to Paris; such a one seeks a servant of such a quality; such a one a master; such a one such an artificer; some inquiring for one thing, some for another, every one according to what he wants. And doubtless, these mutual advertisements would be of no contemptible advantage to the public correspondence and intelligence: for there are evermore conditions that hunt after one another, and for want of knowing one another's occasions leave men in very great necessity.
