Mark Zuckerberg remains the only Facebook originals involve in the day-to-day operations of the social networking giant - all the others have gone setting up their own tech babies following the attachment of numerous zeroes on their names.

One of them is Dustin Moskovitz, who conspired with Mr Zuckerberg in putting together the codes that run behind Facebook, leading to the estimated $US4 billion that the company has so far delivered to his personal bank account.

Mr, Moskovitz, however, opted to end his active participation with Facebook on 2008, according to The Associated Press (AP), and recruited his Harvard University buddy Justin Rosenstein to set up the San Francisco start-up firm Asana.

Asana, according to the Facebook co-founder alludes to a specific yoga pose but his firm deals with customised softwares that allow clients online management of their ongoing tasks and projects.

In a nutshell, Mr Moskovitz described Asana's core functions as providing the solution for a 'meta-problem'.

Asana, Mr Moskovitz said, will give people the liberty they need to enjoy the responsibilities currently at their hands as he stressed that "too much time at work is spent doing work about work."

With Asana in the play, the young billionaire claimed people will have more freedom to take on the more important things in life instead of being stuck in a box.

"We could go work on curing cancer. We could go work on building spaceships. We could go work on art projects," Mr Rosenstein told AP, adding quickly that Asana is actually about working efficiently on a number of things at the same time.

The privileges and independence that the Asana workplace exudes were parallel with the incredible achievements of both Moskovitz and Rosenstein, who are still in their late 20s but can live very comfortable lives on the earnings they garnered from Facebook, which they helped set-up in 2004.

Yet instead of living the life in the fast lane, the duo acknowledged that their wealth can be best used performing tasks that could lead to the betterment of how man lives.

Despite having hundreds of millions under his name, Mr Rosenstein said he prefers working and "when we think of work, we think of work as an act of service, as an act of love for humanity."

The idea of withdrawing into early retirement and simply relishing the comforts that his billons can buy never crossed his mind, Mr Moskovitz revealed.

"If we were just retired, we wouldn't be serving anyone," the man who co-authored the initial Facebook codes with Mr Zuckerberg told AP.

The duo's notion of service also includes establishing a conducive working environment for their Asana employees, which according to AP presently enjoy free meals prepared by a chef and sign-in bonus of about $US10,000 that they can use in acquiring their dream work station.

Such generosity, Mr Moskovitz said, should create an environment in Asana where workers would be more focused in completing their assigned tasks because discomforts and distractions were somewhat minimised if not totally eliminated.

"We're fortunate not to have things that would distract us from being able to act," Mr Moskovitz admitted.

And he is far from being distracted in starting over again as he shared that Asana has so far attracted the attention of prominent names in the tech world namely Foursquare, LinkedIn and Twitter, which have recently deployed the Asana system on their respective workplaces.

The company, Mr Moskovitz added, has seen capital injections that pretty much ensure its existence for quite some time.

And adding another milestone to his already illustrious career, inevitably enriching him further, only convinced the Facebook co-founder to answer the challenge earlier raised by Microsoft's Bill Gates to his fellow billionaires.

Mr Moskovitz intimated to AP that he's ready to part ways with most of his fortunes and give them to charitable works, in line with Mr Gates' call.

His wife, in fact, was already working on a foundation that will act as the main channel of the Moskovitzes' humanitarian efforts, AP wrote.
