For the power users out there, this isn’t even remotely interesting, since you all use TweetDeck, Twhirl, or any other kick-ass desktop client that already understand these things. But web interface users who wanted to catch up on mentions have been forced to search, since the @replies link in the sidebar just listed tweets where you were @username’d at the beginning of a tweet.
In your Twitter sidebar you’ll now see your own @username tab. When you click that tab, you’ll see a list of all tweets referencing your account with the @username convention anywhere in the tweetโinstead of only at the beginning which is how it used to work.
About time. Do follow @blogherald on Twitter, and why not follow me (@tdhedengren) as well?
