The new comment system is a little off-putting (I don’t know why they felt the need to get rid of the share button), but it shouldn’t be too disruptive. You still just type your comment and hit Enter to send, and if you want to start a new line in the same comment, just press Shift+Enter. Easy, right?
What’s even cooler is that you can now edit your comments after you make them. To do so, just hit the little X in the corner of your newly minted comment. It says it will remove the comment, but once you click it, it will actually open your comment back up for editing. It looks like this only happens within the first minute or so that you’ve made the comment, and before someone comments after you, but if you make a typo (or say something overboard in an internet-fuelled rage), it’s nice that this option is hidden away there for you.
