interesting as a lot of twitter (power) users use tweet deck and Facebook is going the same way...  anyway I'm interested in whether to develop 7 learn HTML5 over xaml based stuff...  has anyone any good references...?  for me it's about what the end user experience delivers as that's what people buy into... end users don;t care about the effort and cost of development....  do I go HTML5 or employee iOS/Android/WP developers seperately?...
