When Internet has turned to P2P from client-server model, the network's relation changes, too.
Yahoo, once famous as the portal, now thinks bigger in setting up social network. It has bought upcoming.org to enhance its strategy to manage people's social calendars, share information about upcoming events like local concerts and festivals.
Upcoming.org's idea is fantastic; but I am afraid how it is developed after being bought. M&A sometimes helps dinimishing, hope not this time.
