This lack of activity is exactly like last year, except that last year I was very worried about it.
Now I think of it as the natural ebb and flow of the field. There are fewer questions just at the beginning of summer break, and (iirc) things pick up in August.
Interestingly, if the future resembles the past, our visits only moderately drop during July, but posts drop a lot. Posts resume their normal in August.
Our biggest precipitous drop in all activity is during the Christmas break.
They're both fairly bad CSEd questions, but it seems like to some extend, getting eyeballs is good in and of itself, and most people can get a sense of what we do by looking around anyway.
