Just dropped by the Google Health Beta site that appeared last week – it’s gone.

Either Google achieved its goal of generating some early buzz – is this a new form of viral marketing? – or they an inadvertently released this landing page and had to do some retrenching. My hunch is that it was the former, with Google simply testing the waters in advance of its probable released at the end of February during CEO Schmidt’s keynote at HIMSS.

What I’d really like to know at this point though is what is going through the minds of investors in some of the smaller PHR companies now that they have seen what Google intends to offer.
