When you enter a topic through a link to a post further down in the thread you often need context in order to understand that post. It’s fairly easy to figure out the topic title and the post to which the post is replying. What I sometimes miss is information whether the author of the post is also the author of the OP. How about providing some visual hint about this on every subsequent post of the original poster?
I don’t have a good solution yet but would like to put this out for discussion. So, for example, the visual marker could be an icon next to the authors name or before the title but it could also be more subtle like changing the way the name is displayed or so.
