Prismatic learns from everything you do. We have implicit signals (when you recommend, share, shave, remove, or click), and explicit signals, when you follow topics, publishers, or people. We know more about your interests than anyone, and you can expect that to be more true over time. Fortunately, we are only partially evil, so we mostly use this information to make your life more interesting, and only occasionally, we will use it to troll your newsfeed! :-P

I'm OK with Prismatic using information from twitter and any activity on getprismatic, and but i would not share the rest of my browser usage. For instance there was this day when i was reading up on XML on the browser and opened a bunch of pages on it. Then i fire up getprismatic and lo and behold! i find XML tagged suggestion. That was spooky;)

we don't look at browser history, but we may release a browser plugin for chrome that lets you share, recommend, and save stories from the web to prismatic.
