Google Google have created a new HTTP-based protocol "SPDY" (pronounced "Speedy") to solve the problem of the client-server latency with HTTP. "We want to continue building on the web's tradition of experimentation and optimization, to further support the evolution of websites and browsers. So over the last few months, a few of us here at Google have been experimenting with new ways for web browsers and servers to speak to each other, resulting in a prototype web server and Google Chrome client with SPDY support."

oh... yes... lets use UDP so we can get half a webpage... a corrupted ssl session, non-working or wrong working sites.

Yes... UDP is the solution to everyone's problems.

oh wait no... its not because it is a mindless protocol that does not care of something important is lost or if it is wasting its time sending the data to the other end.

You can implement detection and retransmission of lost packets on top of UDP. The problem is the in-order transmission of packets in TCP. Because of it when you loose a packet all received packets will wait till the lost is retransmitted. With UDP you can use the data in the new packets right away, no matter if an older packet is missing and has to be retransmitted.
Imagine the situation where you are loading many images on a page simultaneously, a packet is lost and because only one TCP connection is used - all images stall till the lost packet is retransmitted.
