Can anyone explain the difference between the gray and blue unread counts?
I can see the gray one is “you have x unread posts” and the blue one is “there are y new posts since you last read it”. I think I understand what those mean, but sometimes the blue count is higher than the gray count:
- Am I correct in understanding that if I scroll half-way down, the gray is the number of posts I haven’t seen (but were there the last time I was on that topic), and the blue is the number of new once since the last time was on that topic?
- Does one of these numbers include the other as a subset, or are they mutually exclusive counts?
