Two observations.
The pop-up flyout that appears when the cursor is hovered over
a user's profile name would previously display only the threads
that were initiated by that user, now all of the user's recent activity
is displayed instead.
Adding the reply that the original poster has designated as the
'correct answer' to the original post is an interesting function,
but it can be detrimental for a user who may not read the subsequent
responses that provide more complete (and often better) information
regarding the problem in question.
A skimmer may only read the original post with the 'correct' response, and
not gain the benefit of of the nuance and corrections that usually follow.
Also, it is often the case that the OP does not recognize a response as
incomplete or not entirely incorrect, and designates the post as 'correct'
anyway.
