I understand where you're coming from, but let me enlighten you as to the reason for using it. The Two Hoots childrens' books (look them up) were favourites of my 3 daughters, well over 30 years ago - and they are about, naturally, 2 owls. Myself and my youngest daughter are, and have been for many, many years, season ticket holders, and when I told her that I was going to have an account on Owlstalk, she came up with the user name.
It originates in American slang as a "hoot" meaning the smallest kind of worthless object. Originally as don't "give a hoot" (singular)
By the way I certainly do give 2 hoots.
Hope this helps
