I've been spending a lot of time on airplanes recently so I killed the time by hacking together a little comment section for my blog. I wrote my own CAPTCHA from scratch, we'll see how much of a mistake that was.
For now I'm keeping it very simple but maybe one day I will add more features like image uploads and mentioning previous peoples' comment IDs in your comment. The way I'm imagining it is loosely inspired by 4chan.
Try it out by leaving a comment on this post!
