Compare the question "What does persay mean?" with "Is it peek, peak, or pique?". Both of them are about common errors and while the former is not as well-formulated as the latter, it has nevertheless been closed while the latter has not. That said, I dare say that persay for per se is at least as common as peak for pique and this is evident from the fact that its question has received ~4000 views in 11 months. That does not sound "too localised" to me.
So, should the persay question have been closed? Or should the pique question be closed? Considering the number of views it has garnered, should the persay question be reopened and perhaps cleaned up?
