This is a really cool idea. It's a really simple solution to the same problem that would be really beautiful and easy to use on mobile especially. It doesn't quite reach the same depth, but I think it's a good way to start.
Always had it on my list to build a prototype of the concept and pitch it to media companies. Baffles me that they do so much work plugging Twitter handles for newsreaders, journalists, etc but then use a platform that hardly helps them.
