The great news about eSteem App, and the programmer behind it, is that he's somewhat a perfectionist... (even if he doesn't realize it).
When he codes something, he feels the 1,000's of users using the app, and waiting for its next update. He does it because he can, and he enjoys when people use his creation.
He is even happier when people appreciate the work he's done, by downloads, upvotes, or even just compliments in comments.
I don't know good-karma in person. But I don't have to.... he gives a large portion of his life for others.. in what he does.. the long nights he spends doing what he does.
He's an app developer that talks to the users. He's not hidden behind a wall. He's approachable.
App developers like good-karma is someone I treasure, and we need more people like him.
Just look at his website: https://esteem.ws
He even puts a link:
https://steemit.chat/direct/good-karma
Who does that? --- A sincere developer, who is happy and interested to connect with the users of his hard work. This is rare.
