Looking to make the web a faster place, Google develops SPDY as a alternate to HTML.
Google’s Plan to Make the Web Twice as Fast
They reveal they’ve already got a prototype web server and a Chrome client with built-in SPDY support that they’ve been testing in the lab. With these tools they’ve reportedly been able to see an up to 55% speed increase in page loading, and feel like the project is now stable enough to warrant soliciting feedback from the web community.

Looks more like an HTTP replacement?
thats damn great and good!!!…was expecting something on such lines for a long time…HTML is way to cryptic and unpredictable…due do compatibility issues…
