Who is the owner of the @stevejobs twitter account?

Since Steve Jobs is dead, a lot tributes show up on the web. And especially on social networks like Facebook and Twitter. The question is, what will happen to the Steve Jobs Facebook and Twitter accounts?
On twitter lots of users are quoting @stevejobs. But if you get closer to the @stevejobs Twitter account, it seems not to be an official one.

Indeed there are no picture, no description, no updates no nothing except more than 15k followers!
So who the hell is the owner of this @stevejobs account and what is he planning to do with?
