Fjax - the new web trend?

Ajax changed the web development and made many other methodologies look conventional.
Now there's another one called Fjax successor to Ajax as many people like to call it. Fjax is a combination of Ajax and Flash. It's fast, compact, and uses less resources than Ajax.
Fjax is an alternative method for doing the kind of Web 2.0 builds that are currently done in Ajax. The advantage is that it does it in a fraction of the size, and requires no code forking to work in the different browsers.
