Facebook announced Wednesday morning that itsis now live to all members, over two weeks after it first debuted to a limited number of users.
It was clear that Facebook was concerned with the stability of the chat application, firstwhen many members--not to mention tech bloggers eager to report any flaw or bug--might not be at their computers.
The social network then rolled out Facebook Chat incrementally, with different "networks" on the site--geographic regions, colleges, companies--gaining access to it before others so that the new feature could stay under control. Some had the feature as early as April 6; a number of large networks couldn't access it until very recently.
Facebook now has nearly 70 million users.
