He points towards a possibility in the near future for the site to support full-bodied text tweets that are searchable and can be highlighted by users without a strict 140-character restriction. Back in August, Twitter removed the same limit from its private messaging system, and a month later new rumors about the possibility for the same move for traditional tweets began circling.
"At its core Twitter is public messaging. A simple way to say something, to anyone, that everyone in the world can see instantly. We've spent a lot of time observing what people are doing on Twitter, and we see them taking screenshots of text and tweeting it.According to people familiar with Twitter's plans, speaking with Re/code, the project is referred to as "Beyond 140" and has a tentative launch window around the end of Q1 2016. Numbers that have been considered internally by the team range from 5,000 to 10,000 character limits, the latter of which would fall alongside the same restriction placed inside of private messages on the site.
Instead, what if that text...was actually text? Text that could be searched. Text that could be highlighted. That's more utility and power. What makes Twitter, Twitter is its fast, public, live conversational nature. We will always work to to strengthen that. And by focusing on conversation and messaging, the majority of tweets will always be short and sweet and conversational!"
The sources point to expandable actions for the new tweets that would keep timelines as tight and orderly as they appear with the current limit, but include an expandable prompt that would then showcase the tweet's full text when clicked. Recently, Twitter updated its site to allow full images to appear without being cut off, and changed the favoriting star to a heart.
