Twitter reveals that it will be possible to publish longer tweets for paying users. So instead of being limited to 280 characters, Blue subscribers can post tweets of up to 4,000 characters. The same limit applies to tweet quotes and replies. Twitter said that in addition to long tweets, people can post media like images or videos.
While only Twitter Blue followers can post long tweets, all users will be able to read them. We will only see the first 280 characters on the timeline, and if we want to know more, we can click on “Show more”.
The introduction of the format means that people buying subscriptions might be tempted to post longer tweets rather than threads. But with non-Blue users still posting chats, it could get messy and confusing.
