Seven Principles of Highly Effective Web 2.0

I very much enjoyed Dion's Thinking in Web 2.0 post. The ways to think in Web 2.0 seem to be growing with significant and useful comments. I would like to propose a side discussion that attempts to reduce Web 2.0 to seven specific principles.

The Highly Effective Web 2.0 is:

1. Specific - Purpose, content and interface is quickly understood.
2. Standard - Data is offered via open standards and protocols (i.e. HTML, XHTML, SOAP, RSS, SSL).
3. Transparent - Privacy and other policies are enforced and simple (see #1).
4. Accessible - Data should be easily found for those with and without disabilities.
5. Interactive - Participation is be encouraged and facilitated (see #1).
6. Inclusive - One thing leads to more like things rather than fewer.
7. Evolutionary - Everything is both familiar and new.

I tend to be overly verbose while clinging to the principle and value of brevity. If we are to understand the Web 2.0 wave, perhaps we can reduce it to seven (no more) principles that are stated simply and without the need for great expansion despite the fact that books may be written on the subject.

Please comment. Let me know which one(s) you would replace, with what, and why.
