This comment is the top Google result for "stack overflow we are less than three people who code". It's not clear to me what you mean.

I think it refers to this[1] page with the header "We <3 people who code" where <3 is supposed to be a heart.

(Probably people from the "post-emoji generation" can't recognise <3 as well as us old people ahah)
