In scrolling Quip’s timeline, a tweet that generated a conversation with people you follow will be displayed as s single tweet, with avatars of users who replied grouped below it. There won’t be separate follow-up tweets in the timeline , as a chronologically-oriented Twitter client would normally do: tweets are grouped by conversation. To show a full conversation, you can tap on the original tweet to reveal its replies, whose authors are, similarly to Favstar, hidden behind a “…more” button when exceeding a certain number.
Quip sounded interesting enough that I downloaded it. I haven’t played with it much yet though.
