The gossip around Facebook's impending initial public offering (IPO) that's expected to take place in the coming weeks, or even days, received another juicy bit of intrigue when one of the firm's founders, Eduardo Saverin, renounced his US citizenship.

The move was immediately cited as a tax dodge by critics, as by taking citizenship of Singapore he is reported to save some $600m in tax on the cool $4bn he is expected to make when the firm's stock hits the markets.

According to the BBC, a spokesperson for Saverin explained the decision by saying he, "found it more practical to become a resident of Singapore since he plans to live there for an indefinite period of time".

While it makes good fiscal sense for Saverin, there is something slightly unwholesome about the situation, as Facebook is cited as one of the shining lights in Silicon Valley's ability to conjure up new, world-changing businesses that make the US as a world-leading tech hub.

For one of its co-creators to give up his relationship with this country for the purposes of saving a chunk of change (admittedly a rather large chunk), seems a touch rash, but as Saverin was actually born in Brazil, perhaps he doesn't have such strong ties to the nation.

It comes just a few days after founder-in-chief Mark Zuckerberg was slated for wearing a hoodie and sandals to a meeting with investors.

However, with both Zuckerberg and Saverin now expected to rake in billions, neither probably care much what the critics have to say about their living locations or sartorial style.

One of the most interesting things about Facebook filing its $5bn initial public offering (IPO) is that it finally provides some hard evidence into the company's success and operating strategies, having for so long been a private company with closed books.

Mostly notably, the firm is already making some strong returns on its advertising model, with revenues up to $3.7bn for 2011, an increase of $1.7bn from 2010, showing the company's advertising-led model is paying off.

However, it is not just advertising that is driving this income, with the firm revealing in the filing that Zynga was responsible for 12 per cent of this income, as Facebook takes a cut of any purchases made by users in the games that run on the site.

Away from the financial figures, the filing with the Securities and Exchange Commission (SEC), also highlights some of the ways in which the company is setting itself up to deal with having to appease Joe Public once they get their greasy mitts on shares in the firm.

The most interesting of the caveats Facebook has placed within its IPO relates Mark Zuckerberg's right to appoint the company's successor in the event of his death.

"In the event that Mr. Zuckerberg controls our company at the time of his death, control may be transferred to a person or entity that he designates as his successor," the filing notes.

However, Zuckerberg clearly has no intention of handing control over any time soon as he's made sure that the share structure of the company works in his favour.

Each share of the 28.4 per cent stake he controls in the firm has a 10 times greater power than normal shares on any issues shareholders vote on, ensuring he retains overall control of the firm.

"[This] provides Zuckerberg with the ability to control the outcome of matters requiring stockholder approval, even if he owns significantly less than a majority of the shares, [...] including the election of directors and significant corporate transactions, such as a merger or other sale of our company or its assets," it reads.

Zuckerberg has also committed to only draw a salary of $1 a year from 1 January, 2013, similar to Steve Jobs during his time at Apple. He probably expects to eek out a living via bonus schemes and share grants.

The firm will also likely be forced to start providing regular updates on the number of active users on the site, which has now been revealed as 845 million, so it may even be the case it can tout one billion members in the run up the firm going public in May.

No doubt that will send already rabid investors into a full-blown frenzy. All this from its inception in a dorm room in Harvard. Amazing.

Steve Jobs and Mark Zuckerberg are viewed as the IT personalities that most inspire people to work in the technology sector, according to a survey from IT jobs site CWJobs.co.uk.

In a turn up for the books, Michael Dell was ranked as the third most inspirational figure, despite having had an up and down year, and even facing a shareholder revolt back in August.

Meanwhile, ever excitable Microsoft chief executive Steve Ballmer and Google's founder Larry Page rounded off the top five.

A whopping 70 per cent believed that the Google co-founder is instrumental in attracting workers to the industry, despite the firm taking a questionable view on privacy issues at various points in the year. Apple (59 per cent) and Microsoft (53 per cent) are also seen as big name attractions.

Some 40 per cent believed that the launch of the iPad alone encouraged people to take up IT jobs, despite the tablet being a little bit overrated in the eyes of V3.co.uk.

Advancement in the field of mobile development, social media, cloud computing and 3D animation are also key factors that have attracted jobseekers young and old to the IT industry.

The survey of 5,500 IT professionals revealed that almost half (46 per cent) feel that the IT industry is a more desirable industry to work in now than it was five years ago. Here, here.

The top five most inspirational personalities in the IT community:
1. Steve Jobs, Apple
