Bob Hertzberg might be gone from the Mayor's race, but he's launched a new website this week to make sure he's not forgotten. Called Big Ideas 4 LA, the site so far has a lively blog that culls stories from the day's news into a snappy, still-evolving digest format. Former Hertzberg campaigner Brian Hay is behind most of the work, and the digests are sure helpful to those who like getting a snapshot of what's happening around the city. But like LA Voice, we're not exactly sure what the point is. Maybe it's the first step toward something big.
