https://stackoverflow.com/about reports that "Stack Exchange is a network of 116 Q&A sites just like it." However, https://stackexchange.com/ reports that there are "115 Q&A sites." (Which agrees with https://stackexchange.com/sites?view=list) And then we have https://data.stackexchange.com/ showing 227 different sites. (Note, however, I did not manually count here. I ran $(".site-list:first > li").length
.)
All in all, how many sites are there?
