Dave Winer mocked up how a fat tweet could look and I think he has it right: http://scripting.com/2015/10/02/whatWouldAFatTweetLookLike.h... Obviously, they've thought of this internally too. I wonder what the point of the 140 character limit is today (I think it made sense originally).
that looks terrible. my favorite part of tweetstorms is the compartmentalization of ideas and arguments. if a point in the story is 50 chars, its 50 chars with a break point. if its 100, let it be 100. making the story one string feel like reading long text, whereas breaking it down feels more comfortable to me. but this is all subjective, and that website's design is pretty sleek :)
That also raises the question of whether a paragraph should be restricted to 140 characters (assuming that's the see more limit) so it doesn't create a see more tweet itself when retweeted, not sure whether that matters.
