via @mashable: Twitter’s Official Analytics Product Has Arrived
Twitter will offer analytics to all users — for free — including information on which tweets were most successful, when people unfollowed you, when you were mentioned and retweets.
While Mashable notes this is bad news for companies (bit.ly) that currently offer analytics for twitter, it’s probably good news for anyone who can figure out how to pull in analytics from across the web (Google, Twitter, Facebook, etc.) into one dashboard and provide some context and connections between those analytics.
That’s a product businesses will pay a lot of money for.
