It's awesome what you're doing. Keep it up. I wanted to do something like that a long time ago but never had the willpower. Keep in mind that HN comments are always going to be discouraging. I find the comments to be 80% discouraging, stop what you're doing, and you suck compared to X. Read them, but don't let it kill your flame. Then double down on the constructive posts that make up the other 20%.
