After posting a Comment to a website article, you can't do edits now.  If you post edits quickly after posting, normally you can do the edit on the comment, but now it bounces you the the top of the article and out of the comments.  If you try to edit a comment after a period of time, instead of getting the normal edit/delete box to request and edit deletion, you get bounces to the top of the article,

You get bounced to the top of the article.  You don not get the opportunity to edit if done shortly after posting, or get the edit request box if the edit is after made later.

SA determines how they order the comments.  The responder only gets to link it to a specific previously made comment.  It becomes a dialogue like a text stream.  Not sure what SA is thinking on how to improve comments, but they are becoming an increasingly valuable information source (albeit with still too many personal attacks).
