Thanks for the extra-reading, I will definately take a look at those. However, I will add that the whole 'pubsubhubbub' thing is very unfriendly (including the silly name) for the people that would be it's most valuable users, ie the people that are generating interesting, novel and valuable online content... ...So in addition to the fact that LiveDirectory is already up and running and working with JSON as the data language, it also aims to make life as easy as possible for BOTH the content publishers AND application developers. Actually, I see think that LiveDirectory is only an intermediate step until website generally get more 'interactive'. What would be cool is to have a standard like: http://somewebsite.com/services.json http://somewebsite.com/services.json (or services.xml) whereby the 'services.json' file would describe what 'actions' and 'data' is available programatically ('search', 'subscribe', 'contact details', 'product catalog' etc). ch, I really appreciate the feedback, this is exactly why I posted this on HN! Please don't think of my response as being in anyway aggressive or defensive :-)
