Re/code: Twitter is said to be building a new product that will allow users to share tweets that are longer than the company’s 140-character limit. It’s unclear what the product will look like, but sources say it would enable Twitter users to publish long-form content to the service. Users can already tweet out blocks of text with products like OneShot, but those are simply images, not actual text published on Twitter. The 140-character limit has been one of Twitter’s trademark features since day one.
