Twitter caused a stir this week when they appeared to trial a new feature highlighting which websites had embedded a particular tweet.
The feature was picked up by security expert Mikko Hypponen, but was just as quickly removed by Twitter, suggesting that it was something that they were merely testing, at least for the time being.
It seems likely that Twitter have developed this feature to support CEO Dick Costolo's desire to help users sift through the clutter of Twitter and find the story behind the tweets.
"That ability to track and monitor the moments within an event, either as they happen or to catch up with them, is something we want to enhance," said Costolo. "We want to make that experience even better, curating the moments within the event, the media from it, and making it that much easier to navigate."
It also seems likely that the new feature will be used for advertising purposes by showcasing the way tweets can drive traffic to websites. It may even be possible that advertisers can pay to appear in the list on popular tweets.
For now though, all of this remains conjecture, but if the move provided a brief glimpse into the future of Twitter, it was an interesting one indeed.
