I think this is the beginning of the end for Facebook.

Let me explain ...

Like AOL, Facebook is a walled garden reproducing what is standard and open on the web/internet as a whole. AOL had AOL email, Facebook has html homepages, and RSS/ATOM

But "people" cannot create their own content - they cannot write HTML, host web pages etc. But contenteditable fixes all that - and with the clever Dropbox tie in, anyone can start with a templated page, drag and drop images from their own desktop, (#) and publish themselves.

Add in RSS via Javascript and its all over.

(#) oh yes drag and drop images onto a web page - its soooo cool. Aloha supports it at least.
