From the Department of Small but Useful Changes:
The MTA's got a new interactive map, though it's so basic you can't believe they didn't have it already. At the MTA.info site, the subway map is now "interactive," meaning you can move it around and zoom in on parts of it, for "easier viewing of fine grain details," as the MTA put it in a press release. Which also makes it easier to view on a tablet or smart phone. Before, there was just a static PDF.
