If you find yourself fighting over the iPad with your significant other to get your fix of news from Zite, there is finally a happy ending to the debate.
Since Zite learns what you like to read and adjusts your personal mix of news accordingly, it was pretty messy if more than one person shared the same iPad. As of today, Zite now allows multiple profiles with a new feature called Sybil, which has the ability to log in to get the news selection that Zite has learned. So if you hand your iPad to someone and they log in under their own profile, the news mix will be personal for that person. There is nothing that prevents a user from having different identities for themselves, so they could change the mix of news and information depending on their mood.
I've always given high ratings to Zite, and the more I use it, the more relevant my news content is. If you haven't tried Zite, which is free, go ahead and download it. If you've been a user, but constrained by other people in the household wanting to use it, those problems are solved.
An October 12 update added source blocking, so you can ban a particular source of news if you don't want it, Twitter integration and some speed enhancements. The new Sybil feature does not require a new download of the app. The changes are pushed out from the Zite servers and were scheduled to be available at 9:30 AM Pacific time.
