Nearly all the BG revenue is from the print edition. Boston.com does not generate the revenue needed to support a newsroom like the BG has.
Like you, I am not concerned if journalism switches its delivery mode from paper to electronic. The concern is that news gathering, reporting and analysis continue.
Here's a nice article from Northwestern University's Journalism School:
"Among possible outcomes for the Globe are coming to terms with the $20 million in concessions, further reducing its staff and scaling back printing. The newspaper could also find a buyer that would support its cost structure or look to alternative business models.
One such model is an all-online operation, which Nieman’s Benton said may not be worth it when nearly all of the Globe’s revenue comes from print circulation.
Boston.com is strong asset, he continued, “but not the type of asset that could keep the Globe newsroom operating as it did historically…If they went online, they would have to completely gut the newsroom.”
Parker, who is an economist by training and cofounder of Mother Jones Magazine, also expressed concern over an entirely online model. While there is an initial burst of traffic to an online news site, visitors fall of drastically shortly thereafter, he explained. "
