Some questions about Grid-Group Cultural Theory

Here’s some provocative questions about Cultural Theory from Y.  Before I attempt an answer, I wonder if anyone else reading this has an opinion or comment…

1. is the theory considered to be a post modern one?

2. does it have prestige in the academic world or is considered niche theory?

3. do you think that online/virtual communities on the internet can also be classified according to the grid group (like wikipedia, linkedin etc)?

Any thoughts?
