Social media site Twitter is changing the way it displays messages.
The microblogging service will now let popular tweets related to people you follow show up first in your timeline, followed by the real-time feed most people on Twitter are used to.
The new "Show me the best tweets first" feature is optional and users can stick with the familiar cascade of chronological tweets if they prefer.
Twitter's existing "while you were away" feature also highlights tweets from the recent past.
The new format aims to inject new life into the struggling messaging service.
The Twittersphere had erupted over the weekend on rumors Twitter was changing to look more like Facebook's newsfeed.
Twitter CEO Jack Dorsey was compelled to tweet that the real-time stream will not change.
Pressure has been building on Twitter to accelerate user growth, and its stock has declined significantly.
