Fast Company:

Twitter is rolling out a revised version of the timeline that indeed shuffles around some tweets into an order that isn’t purely reverse-chronological—but it doesn’t blow away the old format in the manner that had some users writing obituaries for the service.

I spoke with Michelle Haq, a Twitter product manager in charge of the timeline, about what’s new. Without further ado, some questions and answers.

Reading this, you can understand better how and why Twitter is making this relatively minor change. The good news is that is opt-in – if you’re like me and don’t want Twitter to “curate” your tweets, you won’t see any difference.
