Twitter quietly adds clickable stock symbols
 

It might not pack the same thrill as the rumors of in-feed video, but Twitter has added clickable stock symbols on tweets. This now throws up search results for both the stock and the company, using a new 'cash' tag, like $FB, to differentiate from typical links and tags. As noted by TNW, it's bad news for the founder of StockTwits, a service that offered similar functionality to gather tweet-based financial nuggets. The new feature is live across Twitter's web client -- though it hasn't hit TweetDeck just yet -- and should make discovering exactly how many millions companies have made (or lost) all a bit faster.
