I've been running http://gkapp.com/ http://gkapp.com/ since 2010 and http://uselocksmith.com/ http://uselocksmith.com/ since sometime last year - they're both content protection tools for Shopify.

I got lucky, but its success (five figures annually since then) has pretty solidly convinced me: there's value in solving your own problems and sharing the solutions. (And also that Shopify is a solid platform to work with. I love you guys.)
