Google maps mashup site Startup Warrior bills itself as a tool entreprenuers can use to "find a startup job, explore your neighborhood, or decide where you should start your own company." But we feel the site is best used by wary VCs, hassled journos and cynical M&A types looking for regions to avoid. Be warned: Enter into any of the ten regions mapped below and suffer elevator pitches, pleading looks and limp handshakes at your own risk. Update: Apparently Startup Warrior didn't do much in the way of researching the actual addresses of these startups — many are listed by only by city and state, leading to clumps in central neighborhoods.
