Not curt and blunt at all - it's a very good question.

Yep I have, though I haven't done any real marketing. Over the past few months I've come to realize that's one of my real hurdles - marketing is just not one of my skills. I'm not sure where to begin with it, though I plan on learning.

I mostly share on sites like this, reddit, and forrst. Next week I'm going to be presenting Whoops in a lightning talk to a local Ruby group, which isn't something I've done in awhile and which I'm very mentally resistant to.

Maybe it's all just a matter of not having the right knowledge or experience. Programming is easy - I always feel like if I can't see the path I'll eventually be able to find it. Same with UI/UX. Not so with marketing, getting feedback, and iterating.
