A lot is happening at the largest professional network portal –LinkedIn. The website that was launched in 2003 now has over 50 million members spanning more than 200 countries and territories worldwide who entrust their professional identities and relationships on LinkedIn.

Opens for Developers
In order to leverage the professional networks of the users, LinkedIn opened its platform for the developers worldwide earlier this. The Developer.linkedin.com allows the developers to integrate LinkedIn into their business applications and Web sites.

During past months LinkedIn has partnered with companies like IBM, Research in Motion, and most recently Microsoft. Through these alliances LinkedIn has supported integrations with some of the most prominent and critical software applications in the enterprise. “We look forward to seeing the integrations that developers will launch in the coming weeks and months,” says LinkedIn in its blog.

Hits 3 million members in UK
Further, the professional networking portal has registered 3 million members in the United Kingdom. In order to celebrate the milestone achieved, the Company had a grand bash that was attended by various members for the website besides, the co-founder Reid Hoffman and the Managing Director for LikedIn’s European operations Kevin Eyres.

Kevin Eyres writes at LinkedIn Blog, “Without you, there would be no LinkedIn. Our team in London has grown alongside the membership and, thanks in no small part to the great reception LinkedIn has had in the UK, we’re now looking to further expansion into Europe.”

Likely to file for IPO
LinkedIn might pursue an initial public offer (IPO). The co-founder and Executive Chairman for the professional networking portal Reid Hoffman told Reuters that the Company might file for an IPO sometime in future, but not soon. The information was passed on the sidelines of the aforementioned celebrations for marking 3 million members in UK.

"Probably at some point a balance will occur when that's the right thing. That will not occur in the near term," Reuters quotes Hoffman.

The networking portals are being seen as potential firms to go public soon with increasing people riding on the online networking bandwagon. Though, Linked is the most prospective of them to file for an IPO with being a profitable firm from past few years.

LinkedIn was valued as a $1 billion entity during its last financing round in 2008 where the Company brought in around $76 million of investments. LinkedIn is backed by Goldman Sachs (GS), McGraw Hill (MHP), SAP Ventures and Bessemer Venture Partners.
