I just visited the Monastery Gates for the first time in a while and I noticed that the number of replies is incorrect. I checked several of the nodes on the front page, and all reply counts were off.
For example, MS SQL problem shows 9 replies on The Monastery Gates, but I only count 6. 2 of these six are second level replies.
Update: Just did a very quick check on SOPW, Discussions and Meditations and those counts look good.
Update: Looks like it has something to do with the "Show count of all replies" option at user settings
