Great post but taking your Twitter example why not make a full HTML version like GMail does so you don't have to scrap the client side stuff? Also so you don't have to build a framework specific server library like Fastboot. I feel like Fastboot is a more sensible solution than lets say Meteor.js; however, it is still about solving issues for a minority of your users who are on slow internet and older devices. If your really using slow internet and old devices than the experience is still going to be slow no matter what you do unless you really strip things down. So just make multiple experiences that are really good instead of one 'meh' experience. With that said, Twitter made the right decision at the time because their client side implementation sucked on all machines not just the old ones.
