I'm just getting a whitepage with "SF Life" title, fwiw, which is triggering a massive irony reaction. ;)

"Why don't people scale a little before posting a Show HN", I always wonder...

+1, It's understandable when websites aren't perfect across browsers, but when they don't work at all it just seems lazy.

Use Chrome. It only works in Chrome.

why is it limited for selecting three features?

I would love to hear feedback on your experience with the service. davida[-at-]il.ibm.com

The Watson API limits feature * dataPoint < 2000

The limit is only when you use the query param generate_visualization=true (which is the default :)), since you dont show the visualization, e.g. you dont use our Tradeoff Analytics client side code, you should go with generate_visualization=false. If you do choose to use the visualization, please note that the the actual limit is feature* "top data points" < 2000. Your data points size might be 5000 and still our analytics will find that the optimal data points are just 100...

That's great to know! I'll share this info with the team. Opens up the API a lot more :).
