I played around with Prismatic before but it just didn’t grab me and I found I didn’t use it that much.

This new version is a whole different animal. Not only is it much prettier (great design) but they seem to have seriously improved their relevance algorithms. I would be very interested to hear from their data team why the relevance is so much better now - anyone from Prismatic monitoring these comments?

Glad you're liking it! I'm one of the backend engineers who designed the system. We devoted a good chunk of time this year to improving our relevance algorithms, and I actually gave a talk on exactly this at Strangeloop in September.

Great presentation! Very fascinated by this world and Prismatic definitely appears to be at the forefront of achieving relevance. What I've been kind of baffled by are businesses like Taboola, Gravity and Outbrain. I understand their businesses are centered around placement of "related" or 'personalized' articles of boobs, bikinis, and booze just so you click so they get paid, but do you think behind the scenes they have relevance and personalization technology on par with Prismatic? They have a ton of money and people so you'd think they should be able to recommend genuinely relevant content, but publicly never appears so
