Last year, Twitter updated its service so that photos, videos, and other media wouldn’t count against your 140-character limit. Now it’s excluding another feature from that limit.

Twitter is now rolling out an update that excludes usernames from your tweet’s 140-character limit. This means that you can tag as many people in your tweet as you’d like, but still have 140 characters for your actual message.

With this change, Twitter is also tweaking how usernames are shown when you’re @ replying to people. Now you’ll see “Replying to…” followed by user names at the top of your tweet, rather than a long string of user names in the tweet itself. Tapping this will show you exactly who you’re replying to.

This is a nice change for Twitter. Previously, replying to other people would take up some of your tweet’s 140 characters, which could make it harder to say what you want or force you to spread your thought across multiple tweets. With this update, that’ll no longer be an issue.

This update is now rolling out to Twitter.com as well as the Twitter apps for Android and iOS.
