Twitter can’t help itself. If it’s not new pictures, tweet views and video previews, then it could be an epoch-defining change to what the social network called one of its core features: retweets. So, it’s possibly not a big deal, but in Twitter’s latest experiment, it’s been changed to ‘share’ — terminology closer aligned to its rival, Facebook. For the moment, only a handful of users appear to see the substitute share button and it’s appearing in both the Android and iOS apps.

Twitter has been busy making Facebook-like changes today — adding multiple photo upload and tagging, and experimenting with a profile change on iOS — but it isn’t stopping there. Some users are reporting that the retweet button inside their iOS app has become a ‘share’ button — yes, the sacred retweet button! CNBC’s Eli Langer first noticed tweets from users affected by the changes, who are seeing a undeniably Facebook-like experience when they try to retweet content. The actual process of sharing a tweet remains unchanged, but those affected are being asked whether they want to ‘share’ or add comment and share.
