We may never know exactly what Twitter planned to do with its timelines before #RIPTwitter became the most popular hashtag on the beleaguered service, but we do know this: The much talked about experiment is done — at least for two users.

Robin Bonny, a 17-year-old high school student in Switzerland, who first revealed his timeline tester status to The Verge said that as soon as Twitter CEO Jack Dorsey started publicly addressing an algorithm-based Twitter timeline possibly replacing the current reverse-chronological view, he stopped getting the new timelines.

Bonny, who follows only 476 accounts on Twitter — many of them relating to space — told me over Twitter that he has no idea why he stopped seeing Twitter’s timeline test. Nearly a month ago, he noticed the new, algorithm-based timeline on both iOS and his Windows 10 PC. At the time, he didn’t tweet about it (mostly, Bonny retweets).

Here’s how Bonny describes the altered timeline:

They show tweets in several “blocks.” For example, when I scroll through my timeline the tweets come to a point close to now (like 1 h), but then older tweets start appearing on top of those. I think you saw my screenshots on The Verge where there’s a jump from newer to older tweets, this shows this behavior quite well. After I’ve been offline for a few hours there would be 4-5 of these jumps in my timeline.

Bonny is far from alone as multiple Twitter users have reported algorithmically-altered timelines:

Leyawn, whose full name is Leon Chang, told me over Twitter that he, too, first noticed the timeline change in mid-January. And, like Bonny’s, it mysteriously disappeared a few days ago. The 28-year-old Brooklynite has no idea why he was selected for the test, though he wondered if it’s because he’s “some sort of power user.” Chang has 43,000 followers on the service.

Twitter CEO Jack Dorsey has intimated that timeline adjustments might be related to the out-in-the-wild “While You Were Away” block that often appears at the tops of Twitter users’ timeline.

Bonny insists, though, that the connection isn’t quite clear.

“While you were away” still appears in my timeline. The first “block” of tweets up to the first time jump appear to be the most popular tweets so this could be seen as a sort of extended version of “While you were away.” These time jumps also occur after I’ve been offline for an hour or less, even when the “While you were away” box doesn’t appear. So the comparison isn’t always perfect.

Clearly, Bonny is describing a Timeline that’s driven by something more than reverse chronology, a change he mostly didn’t like because it had a habit of scattering Twitter conversations all over the timeline. What it was using to define this order is unclear. It may have been popularity based on retweets and favorites (hearts), or it may have been something else.

Chang, however, noted that his timeline appeared to be heavily influenced by likes and retweets.

Former Twitter Group Product Manager Paul Rosania went on a tweetstorm on Saturday, reminding users that even a reverse chronological tweet order is still driven by an algorithm.

Rosania, who now works at Slack, left Twitter months before this test launched. It seems unlikely he would know for certain what Twitter is or isn’t testing now. Still, he appears to feel strongly that Twitter users shouldn’t be so quick to revolt against possible changes, whatever they may be.

Aside from Dorsey’s blast of tweets, which really only confirmed that the timeline change is not coming this week and that they plan to make the service even more “Twitter-y,” there has been no official comment from Twitter, aside from an official spokesperson declining to comment.

A person familiar with the matter told me that Twitter has been experimenting with the timeline almost constantly, though that person had no insight into the company’s current activities.

One other important detail I learned from Bonny: He could not opt-out or control the experiment. If he wanted to see tweets in traditional, reverse chronological order, he had to either force close the app or reboot his phone. He never found a fix for Windows 10.

Chang’s experience diverged from Bonny’s in a number of significant ways. He only saw the change on Windows (not iOS), found that he could turn it on and off and seems to have encountered a timeline algorithm far more similar to Dorsey’s description. From Chang:

I’m not sure how the algorithm works. It seems to be similar to the “while you were away” feature that most people have. it shows some top tweets that I think a lot of people interacted with.

Still, Chang admits that it doesn’t say those words and the timeline is “definitely out of order.” Chang, who works in advertising told me the altered timeline was “OK. It’s kind of like Facebook. I don’t really need it though.”

Why did the experiment end for Bonny and Chang and did it have anything to do with the #RIPTwitter backlash? Who knows. Bonny seems relieved that it’s gone. “I appreciate that things got back to normal … I’m glad that I got the chronological order back, at least for a while,” he added.
