Earlier quoted context omitted.
Opera is sort of "cute but useless" -- on some sites I maintain for non-technical users, Opera has a smaller market share than IE5. IE6 will probably be around until we're all dead of age.
I'm guessing your not in Eastern Europe? I'm guessing you are in the US since their denizens are famous for assuming the world stops outside their borders. Opera + Chrome + Mozilla (i.e. Theora supporting) market share varies by region but is probably over 50% in every european country bar the UK and that will probably topple with the browser ballot.
Why do Opera users always say something like this? "Opera (and the important browsers) has some huge market share!" 0.2 + 18 + 43 > 50, but the 0.2 really doesn't matter.
