When John Edwards started tweeting five years ago under the Wedge Live! banner, he focused on planning and zoning issues in the Lowry Hill East neighborhood (aka “The Wedge”) in south Minneapolis. Now he’s casting a wider net across the metro. One public official’s bid to steal the “Wedge Live” brand backfired, bringing him even more attention. Edwards has an unapologetic pro-density bias: he’s also cofounder of the Neighbors for More Neighbors group. Edwards’ take is rather mainstream in the context of current city politics, but if a blogger starts rattling the establishment, that’s usually a sign he’s hit a nerve.
