It's Halloween in Silicon Valley (and presumably everywhere else), which means tech companies are turning their corporate campuses into moderately spookier versions of their normal selves.

Halloween seems to bring out the inner bigot in fashion designers, football coaches, and Hollywood C-listers. Apparently it has the same effect on technology corporations as well. Google some version of "Halloween costumes for interracial couples" and this incredibly offensive eBay page with two people in blackface will pop up near the top.

At least it wasn't blackface, I guess: failing Groupon clone LivingSocial hosted a swarm of Washingtonians in its offices this past weekend, and didn't think decorating a "sin of greed" room with dreidels would bother anyone.

When I arrived at the startup house, I walked downstairs and was greeted with what looked like a basement ripe for a party I would have loved in college. The only problem was that there was no one there—seriously not one person.
