Wonder if this will just be a storm I a teacup and it won't really change.
In similar vain to what @Werewolf mentions, whilst he won't have shareholders to please it's still a business that needs to bring in the advertising monies, so I doubt he'll want to rock the boat too much. And if he does then it'll likely spark issues with various governments; i think the EU have already stated they're keeping an eye on him/Twitter going forward.
To be honest, i give it two or three years before he sticks it back on the market after the ePeen of owning a social media company fades.
