Twitter's 140-character limit on posts is both good for the social network and annoying for users. Increasing it too much could change the network for the worse, but increasing it slightly seems reasonable. Twitter is going to alter the way posts work so that links and photos no longer count against the character limit, says Bloomberg.
Just through that change, users will receive a bit more space when they're linking to media or another site. URLs currently take up 23 characters, which is a lot when you're only dealing with 140.
Twitter is said to have considered raising the limit into the thousands of characters, but it decided against that change. This update could be implemented without affecting the network to any notable degree.
