Raising block size has nothing to do with XT. You can stop the propaganda lies now. There's no such thing as centralized Bitcoin development. Anyone is allowed to create any changes they want and have miners vote for it.
Hear hear.
What is happening now was always going to happen at some point.
A fundamental weakness of bitcoin is the reliance on a few human programmers responsible for maintaining the reference client software run by the majority of the network. If a small cabal of people believe they can dictate the direction of bitcoin then as they are finding out to their chagrin the market will sidestep around them.
Bitcoin development has never been so exciting - BU, XT, BTCD, bitpay Core variant and now bitcoin classic. This is what open source is all about. The market will decide and if the market doesn't like 1mb blocks, over complicated soft forks, a fee market and RBF then bitcoin will simply follow another reference client and fork away. I can see the value proposition of bitcoin massively rising if that happens (no doubt significant volatility during the run up to a fork!) as it proves that the project cannot be coopted or changed by a few men - no matter their motivations - or indeed the outcome, whether it be continuing with Core or another team(s) instead.
EDIT: becoin you sound utterly preposterous trying to label other implementations of bitcoin clients mentioned above 'alt coins'. Such dishonesty simply marks you out as an unreasonable thoughtless drone.
