Very interesting interview overall. Philip notes that he didn’t see weblogs coming because ‘it never occurred to me that relatively minor changes in how you allow people to author would cause such a revolution’. I must admit, I was the same. As far as I could see, it was just another HTML page, being updated frequently — it took me quite a while before I realised the social aspects, of conversations taking places in a group of weblogs, was making a whole new thing.
Also, there’s a great few paragraphs where he discusses how sensitive to supply-side economics the whole ‘building a business on open source’ thing is. Search for ‘a dollar cheaper and a day faster’ to find it.
