Twitter does a lot of things well, but it hasn’t really nailed context yet — or search. After you first join the service, it takes a significant amount of following and unfollowing before you settle on a stream (or Twitter hose, as some call it) that works for you. Search, too, is noisy and generally unhelpful. In May, Twitter started to test some personalization features to start making better suggestions in terms of who to follow, etc., and it continues to improve search and “Discover.”
In the meantime, a newly-launched platform called Twtrland wants to give you a simple way to figure out whether or not you should follow, along with a new way to search the Twitter graph.
