I've been noticing this happening lately...I don't see threads until they are several hours old. For example, this evening, at about 8:50, a new thread appeared (Calif woman gets 6 years for fatal texting crash). I clicked on it only to find there were already ~12 posts in it, and that it had started around noon my time. I've been on several times off and on today, but this is the first I've seen this thread. Makes me think, how many threads am I missing altogether?
