The new post activity div which gives info about the number of questions on Stack Overflow says
1 new questions
This is grammatically incorrect, but only in the case of 1 question; if there are more than one questions, of course this phrase is grammatically correct.
Also, this is only in the case of SO. On other sites this div seems to be working okay (because they are still on the old navigation for me perhaps?).
However on other sites, the title of the question seems to be incorrect.
