A weird role reversal. Many of the tech communities on Reddit are garbage.

Then again, my first question upon seeing this on HN was "how on earth is this relevant/interesting? It's not even finished!" so discovering that the source for the submission was a tech subreddit is unsurprising.

From what I've seen, /r/programming is about as bad as any. But people read it anyway because there isn't really a better programming subreddit. (Some of the very specialized ones are better, like for specific languages, but the wide-audience subreddits seem to be full of people who do not have much experience and are more interested in one-upmanship than in talking shop.)
