Eightmaps

An interesting story, about "eightmaps", a site that takes the names and ZIP codes of people who donated to California's Prop. 8 — information that California collects and makes public under state campaign finance disclosure laws — and overlays the data on a Google map:

FOR the backers of Proposition 8, the state ballot measure to stop single-sex couples from marrying in California, victory has been soured by the ugly specter of intimidation.

Some donors to groups supporting the measure have received death threats and envelopes containing a powdery white substance, and their businesses have been boycotted.

Intimidation is bad, of course, but we're supposed to think that disclosure and transparency are good, right?  So, what about this?
