Update:

Now Nintendo of America has issued a press release (which popped up in our inbox minutes after original publication), explaining how a 'Hackathon' at Facebook will determine the stage that'll be included in the game.

Hackathon events are a unique element of the Facebook company culture, and an opportunity for employees to pursue a project outside their day-to-day responsibilities to rapidly create something that interests them. The Super Mario Maker hackathon is exclusively for Facebook employees to design a special level in the game. At the event, participants will be using the demo version of the game that drew rave reviews at the recent E3 video game trade show to create levels using the in-game tools that will become available to a wider audience when the game launches exclusively for Wii U on the 11th of September. The event will culminate with designers presenting their creations to a panel of judges from Nintendo and Facebook. The winning individual or team has the opportunity to make the level available for Super Mario Maker owners to play after the game's launch. Nintendo will be making a video series documenting the event available for fans to view shortly after the event concludes, and fans can also check in to Nintendo's social media channels on July 28 and July 29 for live updates.

It seems like a neat bit of publicity and, as we've said in the original article below, appears to be a smart move by Nintendo.

Original Article:

Most of us have deleted a tweet and hoped no-one read it. Perhaps it was a rant, or a revelation that shouldn't have been shared, or perhaps you're like this writer and is always trying to hide evidence of awful typos. Unfortunately for Nintendo of America - or fortunately, actually - it has 1.85 million followers, so can't delete a tweet without it being spotted first.

That's the case with its announcement - then deleted - of a partnership with Facebook for the launch of Super Mario Maker. The tweets also confirm that a level designed by a Facebook employee will be released with the game.

We believe that second tweet simply means one Facebook employee will have a level picked and shared, not implying there'll be level downloads that aren't free. Ambiguous wording like that may have contributed to the tweets being pulled.

In any case, this could be a smart piece of marketing business for Nintendo, and will no doubt make a lot of noise about it when ready.
