The Columbia Journalism Review launched this year its News Frontier Database, meant to be a curated directory of independent online news organizations, included the two niche sites on which I collaborate.
See the entire News Frontier Database here.
Technically Philly was an early listing, having been contacted by CJR in March and launching in early May. See that listing here.
Northeast Philly hyperlocal NEast Philly was recently added too. See that page here.
Including those two, there are just four Pennsylvania sites listed, all from Philadelphia, including also PlanPhilly, with which Technically Media is now doing some work, and another FactCheck.
