BOSTON — As the final daily issue of the 100-year-old Christian Science Monitor was put to bed Thursday, the newspaper was planning its rebirth as a spruced-up weekly. Meanwhile, the Monitor's free Web site will get more frequent updates from dozens of its reporters, who will be expected to quickly post material to the site and take video and gather audio. Editor John Yemma hopes these changes will help the seven-time Pulitzer Prize-winning newspaper boost its $12.5 million in annual revenue, even with the recession.
