I've been always afraid of posting to such resources as Reddit or Hacker News.
Because of this "imperfection syndrome", when you know that no everything works in your app, you have bugs and all that stuff.
But for some reason, I decided to post to subreddit, r/webdev.
At first, the post was automatically deleted, because I didn't have enough karma. Then I asked the moderator to approve it manually and he did.
Now the post is on the front page and I already got one life time deal sold!
So excited about it!
