Is RSS the TCP/IP Packet of Web 2.0?

Babak Nivi is writing an interesting series about RSS and its role as TCP/IP of Web 2.0. In the latest installment about Yubnub I made a comment outlining some of the differences between Ambedo and Yubnub. They are:

• Everyone has their own “tagspace”. This means users can have their own tags and decide for themselves what a certain tag should do. So you basically avoid collisions. Still though there is a directory where you can share your tags and also import someone elses. With your own tagspace you can also use it for bookmarks stored on Ambedo. These can then handle things like logins or other repetitive tasks which you easily can access through a customized url.
  
  
• It is based entirely client side - all your tags are loaded immediately in compact JS. With this it is very easy to see exactly what is going to happen before you hit enter.
  
  
• There are features other than tags/commands. There is a built-in calculator and also detects patterns such as urls, isbns, domains, ip addresses etc. This makes it handy for most day to day tasks for me at least. I can type almost anything I want and get it done immediately with Ambedo.
