Greed is both America's driving force and its incurable sickness. One particularly egregious symptom: the obsession with property values. The lust for high-end real estate reinforces old prejudices, creates paranoiac provincialism, and often leads to a stifling conformity that strangles the imagination -- but hey, it fattens the wallet. (Yes, Weston, we're talking about you). All of these facts conspire to make the property appraiser's Website a most delectable pleasure of the guilty variety. The site feeds that unhealthy instinct Veblen called "pecuniary emulation." You usually can't find out your coworkers' salaries, but, on Bill Markham's database, you can damn well learn how much they paid for their houses. Look up your boss and confirm once and for all that the nincompoop is making way too much money. Look up politicians, pastors, friends, neighbors. Find out their square footage and what they pay in taxes. You know you want to know, so get down off your high horse and log on. On a more practical note, somebody told us it can also help gauge the value of a home you are buying or selling. Just remember to follow the instructions: last name-comma-no space-first name, like say, Rodstrom,John (who has a house assessed at more than $700,000 on Nurmi Drive in Fort Lauderdale, if you're curious).
