Company adds twist to timeline

Twitter launched a new kind of timeline Wednesday — one that displays tweets using a Facebook- like algorithm.

The change, which sparked objections last week and caused the hashtag # RIPTwitter to trend globally, is opt- in for now. Though Twitter plans to make the feature a default setting in coming weeks, users will be able to opt out and revert to the traditiona­l reverse chronologi­cal timeline.

If a user enables the option to “show me the best tweets first,” a handful of non- chronologi­cal tweets will appear atop the timeline. The only indication that they are out of order will be the time stamps on the tweets. Users may see as many as a dozen such tweets before their timeline resumes its reverse chronologi­cal order.

Twitter hasn’t outlined the factors that determine which tweets it will push out to its users in the new feature — a lack of transparen­cy that has created mistrust among some users.

In its Wednesday announceme­nt, Twitter’s senior engineerin­g manager Mike Jahr said they will be a sample of the “most important tweets from the people you follow.”

Analysts have not been optimistic about the new timeline’s ability to secure more users — or keep the ones Twitter already has.

The new timeline feature is the biggest change Twitter has seen since Jack Dorsey returned as CEO last year.
