I'll be impressed when there's some reform or change in a powerful country or against a powerful and corrupt leader like Russia's Putin, who is clearly fleecing the Russian people to enrich himself and his friends. So far the only good news of note is that the US and the IRS will be cracking down harder on these characters now that they have all this ammo against them.
Sadly, this will get a lot of people thinking "our side won" when this is pretty much the lowest prize we could have. Where's the real reform? Where's the big leaders being taken down? Iceland is pretty much a suburban Danish city on an island. Its not a world power. My city's dog catcher got more votes than this guy. Lets demand more than trivial wins.
That said, bravo to the Icelandic people. Their example of a more direct form of democracy is pretty inspiring.
