Twitter is testing a way to make it easier to spot the person who started a thread. A small percentage of iOS and Android users are seeing an "original tweeter" label. The company said [engadget.com] earlier this month that it would publicly test some context and organization features.
It's a useful feature, and it could reduce some types of abuse, particularly if the original tweeter is, say, Bill Gates and the replies include those from scammy imitation accounts. The label, along with the blue verified checkmark, could make it more immediately obvious when Gates himself is replying, and not, for instance, @Bi11Gates.
