If you've been following the same people on Twitter for the last five years, you're probably missing out. An engaging Twitter feed should provide an intersection of interests from thought leaders across fields.
For that reason, we've gathered 22 intellectual heavyweights in areas like design, neuroscience, management, and economics. Start following them and get your ideas flowing.
If we missed anybody, tell us in the comments.
