Twitter thrives on its ability to understand both your tweets and the hot topic of the day, and it needs every bit of help it can get -- including from computers. Accordingly, the social network just snapped up Whetlab, a startup that makes it easier to implement machine learning (aka a form of artificial intelligence). The two companies are shy about what the acquisition means besides an improvement to Twitter's "internal machine learning efforts." However, the likely focus is on highlighting the content that's most relevant to you based on your activity and who you follow, as well as hiding abusive tweets before you have to reach for the "block" option. Whetlab's technology could get the ball rolling on these robotic discovery techniques much faster than before, and give you a custom-tailored Twitter experience that requires little effort on your part.
