I get what you're saying, but lifting the character limit doesn't in any way mean you need to write longer tweets. You could still just write off the cuff thoughts when you have them, as the platform currently allows for.
Of course, but I think the psychological benefits to the imposed scarcity are enormous.
I think there are ways to allow tweetstorms without lifting the limit, and I love the concept of things like oneshot that allow you to reference something without making it part of your tweet, but still imposing the limit. My guess would be Twitter builds in some features like that.
