Twitter CEO Jack Dorsey replied to the report this afternoon, via a tweet of his own. In the tweet, Dorsey says that there never were any plans to change the timelines next week. And that is where this story would end, except for a tweet from Josh Sternberg, NBC News’ Director of Branded Content. Sternberg wrote that sources inside Twitter have told him that the algorithmic timeline would be "strictly opt in."
So we are struck with conflicting stories. The good news is that even if Sternberg is right and the algorithmic timelines become available, those who aren't interested in such a thing can continue to receive tweets in reverse chronological order by refusing to opt in..
We should point out that Dorsey was mum about the rumored increase in the character limit on tweets, from 140 to 10,000.
Twitter CEO Dorsey denies that there will be a change to algorithmic timelines
