My point is that many people who make predictions on this topic come to conclusions by fixating on largely irrelevant details. Are people on Twitter because it's a "mirco-blogging service" or because they find funny memes, follow people they like, get information they value, find the UX addicting, and everyone already has it? Unless those core value propositions change (which I haven't seen evidence of) the changes to tweet length, blue checks, metrics visibility, etc won't get users to leave for a more complicated alternative.
