Twitter has introduced a new feature making conversations easier to follow,On the Tweet page, Tweets that are part of a conversation are connected by a line. If you want to see more of the replies to a specific Tweet within a conversation you can click “View other replies”.
On their blog they post the following.
Conversations surrounding a Tweet, particularly if they’ve sparked lots of replies and disparate conversations, can be hard to follow. So, we’re doing a few things to make this much easier: grouping conversations together and highlighting some of the most interesting exchanges surrounding a given Tweet right below that Tweet. To surface some of the most interesting conversations, we’ll take factors into account like whether the original account has replied.
Example – Q&A with Tony Hawk.
This feature is now beginning to roll out to all logged in and logged out users on twitter.com today and will be rolling out to mobile apps in the future.
