WhatArePlatforms (ThoughtStorms)

Context : OnPlatforms

MarcAndreesen distinguishes three types or levels : http://blog.pmarca.com/2007/09/the-three-kinds.html

First he notes that he's only talking about computer platforms meaning things that can be "programmed" in some way (presumably not, therefore, hardware platforms that can play different kinds of video format etc.)

Andreesen pushes his Ning as a level 3 (excellent news, as Ning was always cool.)
