X (formerly Twitter) is an online news and social networking site where people communicate in short messages. The hope is that your words will be useful and interesting to someone in your audience. X is an example of a microblogging platform.

Some people use X to discover interesting people and companies online and choose to follow their tweets.

The big draw of X is how scan-friendly it is. You can follow hundreds of engaged users and read their content at a glance, which is ideal for people who need a lot of information quickly, especially if they only have a few minutes to peruse the feed.

The platform has a deliberate limit on post size to remain scan-friendly: by default, each post is limited to 280 characters or less. This limit encourages targeted and clever use of language, making tweets easy to scan and hard to write. The limit, which started at 140 characters, is what made Twitter (as it was originally called) a popular social tool.
