Jester asks you to rate jokes, and then recommends other jokes to you based on these previous ratings. As you rate jokes, you’re likely to find the next ones more and more funny. In other words, Jester recommends jokes that you’ll probably enjoy. The service was developed by Prof. Ken Goldberg from UC Berkeley and powered by a patented recommendation algorithm known as Eigentaste.
There are all kinds of jokes here, including mild ethnic, sexist or religious jokes. So if you’re likely to be offended by any of them then probably Jexter isn’t for you.
