My Stupid Google Reader Can't Count

Every day it slowly adds to the number of unread posts, so that now, it's more than 100 posts off. If I had zero posts unread, it would tell me I still had 103 to read. (Till tomorrow or Tuesday, when it will surely register at least 105.)

And now, none of the posts I'm reading tonight are getting "cleared" -- they're all still in bold. So now I won't know which blogs I really need to read or not.

Stupid reader.  Isn't counting one of the most basic things a computer is supposed to do? How hard could this possibly be?
