A new Dynamic Address Book service has hit the market.
www.bebo.com -from Birthday alarm guys.

It seems that it is spreading like wild fire www.businessweek.com/the_thread/techbeat/archives/00000056.htm

My take:
Nothing great features wise, plain simple service. Other services like plaxo,good contacts, a host of firms have a much richer interface. Since they have just started, it will be interesting to watch what they bundle in the core service. But I guess their past performance and brand is helping their viral marketing efforts.Can their late entry in to the market be offset by their marketing efforts? Time will decide.
