The news discovery service I rely upon most: Nuzzel. - Sean McBride

The smarter the news discovery service the better. Without a smart news discovery service you won't know which end is up. - Sean McBride

To get the most out of smart news discovery services, you need to cultivate several social media platforms like a garden -- to provide as many key signals and datapoints as possible -- to build up your interest graph. - Sean McBride

For instance, Nuzzel is only as good as the Twitter and Facebook interest graphs you feed it. - Sean McBride

The most important signals you can send to news discovery services: the feeds you follow. Your interest graph is largely the product of that dataset. - Sean McBride
