The blog itself:
The blog says: "The Big Picture is a photo blog for the Boston Globe/boston.com, compiled semi-regularly by Alan Taylor. Inspired by publications like Life Magazine (of old), National Geographic, and online experiences like MSNBC.com's Picture Stories galleries and Brian Storm's MediaStorm, The Big Picture is intended to highlight high-quality, amazing imagery - with a focus on current events, lesser-known stories and, well, just about anything that comes across the wire that looks really interesting."
The blog's FAQ is here. I think it's significant that the BG hasn't walled off its web developers. I think it's pretty common for papers to treat the web as another piece of equipment (like their presses) and the developers as cerebral mechanics. It might be a better model for the news rooms and the tech rooms to merge, as seems to be the BG model.
