Where does Carson Daily obsess over news articles about The Voice? Prior to Twitter's new custom timelines feature, he likely had some kind of scrapbook at home. Now, thankfully, he can put them all in one handy stream, delivered directly over Twitter's platform. The feature lets you handpick the tweets by way of TweetDeck, and the microblogging service is also opening up a beta version of an API that will let developers automate the process. TweetDeck users should be seeing the manual version over the next several days.
