Feel free to put this one in the "foolish consistency is the hobgoblin of little minds" category if you want
Next to each of the individual forum links is a number. On the "full site" the number seems to be the number of unread posts in that forum. On the mobil site, however, the number is "different". It's probably the total number of posts in the forum (I haven't counted) but it's different than the "full site" version...
Just something that I found strange.
