Web group calendar apps

Business social network LinkedIn has given itself a New Year"s makeover a few weeks early: the site has announced a home page redesign and new features, and has simultaneously launched a developer program that it calls "InApps." For LinkedIn, which says that it recently passed 17 million user accounts, this move comes at a time when some observers are saying that business social networks are about to take off in a big way. The redesigned home page has not gone fully live, but is now accessible to logged-in LinkedIn members on a beta page. ***
