NEW YORK (AP) — It was barely a "like" and definitely not a "love" from Facebook investors as the online social network's stock failed to live up to the hype in its trading debut Friday. One of the most anticipated IPOs in Wall Street history ended on a flat note, with Facebook's stock closing at $38.23, up 23 cents from Thursday night's pricing. That meant the company founded in 2004 in a Harvard dorm room has a market value of about $105 billion, more than Amazon.com, McDonald's and Silicon Valley icons Hewlett-Packard and Cisco.
