People in this "digitally connected" world often overlook any product that doesn't produce high DAU/MAUs. It's the single metric driving a huge sector of tech today. Often, digital influence (likes, klout scores, etc) are the symptoms of large amount of gold miners chasing gold bars in the shape of MAUs/DAUs. I don't want to discredit those who do so (it's clearly profitable to some extent), but there is a huge market that doesn't include the $17bil Uber's of the world...industries that have been around for centuries, that rarely get press (because they also don't drive today's eyeballs).

That being said, those same markets have never heard of Haskell, Rails, Erlang, Backbone and the latter, which could in fact drive real solutions for their problems. This is really (IMHO) where real economic value can be had, and the potential is in the trillions of dollars. I like patio's sentiment (not verbatim) of "99% of the businesses out there still don't have web solutions".
