We are 7 full years into Punday Monday, a consistent weekly contest soliciting puns from users.
Today will be the 364th post. We have an average of 3 entries, with some weeks having many more. There are several regulars, several more used-to-be regulars, and many more tried-it-once-ers.
I haven't kept a spreadsheet or anything, but prizes have included HSBI/SBI for many years. I can estimate that I've delivered well over 500 HSBI/SBI units through the contest.
We've taught new people to pun, and encouraged timid punsters. I imagine several people have laughed.
