So, not sure if you´ve noticed, but now, when replying to a tweet, the name appears under or over the tweet and not inside the tweet, this giving more room for characters, yes, you can write more, but not great for "retweet follow" on...
also, the notifications page has changed, now showing a lot more information within one notification, it can be a bit hectic for someone receiving 300 or more notifications every day.
Check your twitter & give your thoughts
