(1) I am sorry that I have no way any more to Follow anybody "back"; there are MANY who I would like to "follow back", but I am at my limit.
No on should feel slighted by this.
(2) I also apologize for often editing posts (esp. Q and A) up to more than an hour after making the posts. It would be nice if my followers returned to my Q or As after about an hour to see what has been added or edited.
