I think there's something to be said for picking up on something popular and doing it well; you don't necessarily have to reinvent the wheel. I recall Pogue's article on walkie-talkie apps (http://www.nytimes.com/2012/09/06/technology/personaltech/zello-heytell-and-voxer-make-your-smartphone-a-walkie-talkie-david-pogue.html?pagewanted=all&_r=0 http://www.nytimes.com/2012/09/06/technology/personaltech/ze...), and how even the best apps had the most god-forsaken interface design. Being incumbent in a space doesn't mean you do a great job at something. Whether this makes Talko interesting and useful remains to be seen (I'm reserving excitement personally), but I definitely think there's a lot of room for improvement that Talko is taking advantage of.
