No, people read threads backwards sometime, you know, entering from the front page with the link to the last post, and reading up (in reverse order posts were made), not down (in the order the posts were actually made), from there... I do that often, sometimes only trying to find the right order when I discover an especially interesting string of conversation, so I can get it in the right order...
I hope people do not think I have something against them because I am not liking their posts in a thread where I have liked other people's posts... there is never any guarantee anyone has read a whole thread, even if they put a like stamp on every response.
