Really having trouble garnishing interest in a tool I built (deltatrail.io) so naturally I was intrigued with this article. Seems like the "I can build this myself" response is common even though I know many would rather not (even if they could). What I think I'm gathering is that, a solution needs to be immediately useful. My tool which is a "this may help you down the line" (it actually will) but doesn't provide immediate benefit. They say it's easier to sell Advil than Vitamins, right?
