Twitter have just announced a new ‘tailored suggestions’ system that is raising some privacy concerns about tracking of web usage via Tweet buttons in a similar vein to the Facebook Like button furore a while back. Presumably the solution is to not log in to Twitter using your browser – perhaps not a problem as most people seem to use their phones anyway. Mac users can also create a custom browser app using Fluid to isolate Twitter cookies from normal browsing, which is what I do with Facebook.
In a blog post today announcing Twitter’s new tailored suggestions system is something that has left me shocked: an overt admission by Twitter that it is transparently tracking your movements around the web. Othman Laraki, on the Twitter blog:
These tailored suggestions are based on accounts followed by other Twitter users and visits to websites in the Twitter ecosystem. We receive visit information when sites have integrated Twitter buttons or widgets, similar to what many other web companies — including LinkedIn, Facebook and YouTube — do when they’re integrated into websites. By recognizing which accounts are frequently followed by people who visit popular sites, we can recommend those accounts to others who have visited those sites within the last ten days.
Basically, every time you visit a site that has a follow button, a “tweet this” button, or a hovercard, Twitter is recording your behavior. It is transparently watching your movements and storing them somewhere for later use. Right now, that data will make better suggestions for accounts you might want to follow. But what other things can it be used for? The privacy implications of such behavior by a company so large are sweeping and absolute.
