I just realized this. When you click to comment on an article or a blog post, you can't go back up to read the post while commenting unless you exit out of the comment window. Unfortunately, doing that deletes whatever you've already typed up. Unless you have something like notepad opened up for you to copy and paste your comment into while you reread the post to better respond to it, you have to retype the whole thing over and over. That's an inconvenience that really should be looked into being fixed.
