Is there any sort of way to cancel out of making a comment? I wasn't planning on leaving a comment right here but now I actually have something to comment about!
When I saw the title and URL, I initially thought that it was an extension to integrate HN comments with the actual articles. That would be pretty cool too.
If anything, it would be nice just to have the top bar that can redirect back to the comments section of the article along with the submitted title. I tend to go through and click a bunch of links and then go through them in order to avoid the "unknown or expired link" error and it would be nice to have a little memory jolt to remind me why I was there in the first place!
I'm not sure if something similar exists for FF, but if you go to the github you'll see that all you need is jQuery and my hnreply.js file, so maybe one of those user theming extensions will let you insert them.
That would be a really cool project, but certainly a lot more work than my <100 line Chrome plugin. Maybe the HNSearch guys could do that, they already pull down all the data from the site. It would also be very hard to get the votes/comments to mirror.
I don't think this is just in the vein of Reddit, but just an interactive experience many expect when using comment forms. There are a few things I wouldn't mind HN grabbing from Reddit (and many more things I want to stay as far away as possible), but this was, by no means, something I thought of as an exclusively "Reddit" feature. While I understand Reddit has this capability, it's hardly specific.
I made this, and here is the Github: https://github.com/hatboysam/hnreply
It's crazy simple, just a little workaround to get the "fnid" code the comment reply page uses to post replies.
Let me know what you think of it.
