In case you have not heard, Facebook (FB) goes public today and its initial public offering makes it the most valuable company at the time of its offering to ever go public. At $38 a share the company is valued at $104 billion.

While demand to own a stake in the tech giant has been much greater than any would have expected, a new AP-CNBC poll shows that 50 percent of Facebook users believe the social media network may be just a passing fad.
