There are almost 200 photos in Flickr tagged with the mis-spelled tag 'Domnica'. Easy to do - in fact, I did it with the very first web page I put up in 97, and suffered for what seemed to be an age every time I searched Google, but it shows the import of spelling. And given that even Firefox now carries a form-field spell checker, it's getting even harder for a typo to slip through the net.
Anyway, that's 200 photos that most people would not see if they were searching for DomInica'. So check your spelling!
