Cool article! I think a broader question raised is one I have thought about a lot: what is the optimum trade-off between narrow clarity of function/purpose and broad ambition/expansiveness/spread of features? On the one hand: we obviously admire and use things that are ambitious and full-featured (google, facebook, etc. etc. etc.) On the other hand though: HS points out that the narrowed "X for Y" model makes a better YC pitch... but more importantly, it might make a better consumer pitch. E.g. sometimes I wonder why I don't use wolfram alpha more often... and I think one of the answers is that I don't quite know what it does. It possibly covers TOO much area and I might- at a moment of quick snap judgement- pick the far more limited service with the easily comprehensible/memorable single feature claim... Thoughts?
