Twitter is rolling out a couple of new features that should help you find more revelant tweets, especially those that involve you.

As of yesterday, the microblogging site is replacing the familiar Mentions tab with a new tab that displays your username, according to the company's official blog. Clicking on your username tab will reveal more than just tweets in which you're mentioned. You'll be able to see which of your own tweets are considered Favorites or are retweeted by someone also. You'll also see tweets directed to you and which tweets are popular among the people you follow.

The second feature rolling out this week is a new Activity tab. Nestled next to the new Username tab, the Activity feature will display the latest Favorites and retweets from the people you follow. You can also see who they're following. It's a way to combine and condense similar information all in one single spot to better discover what your followees are up to.
