Bloggers plan round-the-clock charity drive: This year, 545 participants have enlisted, with US$56,000 pledged so far. At 6 a.m. Pacific time Saturday, they'll embark upon 24 hours of blogging, during which they've agreed to update their sites at least once every half hour. Readers can sponsor participants by offering either a flat cash donation or an hourly pledge, which they'll pay upon successful Blogathon completion to the charity named by the participant.
