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.
