Parent/Content link in threads/replies:
If I get a comment reply, reply to it, somewhere along the way, I can't see what the first reply is replying to without loading all of the comments on the page. Right now, that's not really anything but if a post starts getting a lot of comments, you could get lost.
Keyboard accessibility:
I'm a keyboard fiend. If I can use the keyboard instead of reaching for the mouse, I can. So when I'm doin' stuff, I tab and hit enter. Because, on a web form, enter on a non-textbox control submits the form. So if I hit tab when I make a post, focus goes to NSFW. And it's a form element, right? So hitting enter there should submit the form without setting the checkbox tick, right?
Nope, Chuck Testa. It just sits there and looks at me funny.
Just a thought on that one.
Ok, now say that agin, but this time speak into the microphone.
