Twitter has announced that it is launching major upgrades to its Facebook and LinkedIn applications, bringing added functionality and integration between Twitter and two of the world’s largest social networks.

The new Twitter app for Facebook, which is now available here, not only allows you to syndicate your tweets to the world’s largest social network, but now has a feature that allow users to see which of their Facebook friends are also on Twitter and choose which ones they want to follow.

The new feature could be huge: it brings existing Facebook connections into the Twitterverse, which is likely to spur new levels of engagement and growth. We’ve already seen a fail whale or two in our testing of the new Facebook app though, making us worry that the new feature could potentially cause more downtime.

The microblogging startup is also announcing updates to Tweets, LinkedIn’s Twitter application. LinkedIn beefed up its Twitter integration last month. It also includes a feature that lets you see which of your LinkedIn connections you follow and automatically follow the ones that you don’t.

Linkedin hits 70 million users

Professional social network LinkedIn now has 70 million members, according to the company’s home page. The company hit 60 million users in February, and has been growing fast, especially in international markets. LinkedIn’s network’s CEO, Jeff Weiner, stated in a blog post last fall that half of LinkedIn’s membership is international. The company is also listing one million company profiles, which are similar to a user profile.

Weiner tells us that the fastest growth LinkedIn is seeing is in international markets.
LinkedIn has mitigated the growth in international markets with expansion in international offices in The Netherlands, and India, two areas where LinkedIn is growing rapidly.

The network has also been adding features continuously over the past six months to broaden LinkedIn’s reach across the web, adding a deeper Twitter integration, opening up an API, providing a plugin with Microsoft Outlook and enhancing sharing options.

But while LinkedIn is looking to bring its platform to the greater web, there’s a tremendous amount of potential to use the data the network has on its side to add additional functionality to both users and companies. Weiner recently told us that data is incredibly important part of LinkedIn’s future as a network. And while we can’t reveal what those data features are at the moment, it’s safe to say that we will be seeing a number of new initiatives coming from LinkedIn leveraging the wealth of professional content on the network.

Weiner won’t comment on any plans for LinkedIn to IPO in the near future, but the company is clearly seeing growth, is profitable and working diligently to build features into the platform. It should be interesting to see what the second half of 2010 brings the professional social network.

LinkedIn launches API

As rumors continue to swirl around LinkedIn’s possible IPO, the professional social network is steadily adding useful features that help transcend the platform’s technology into other applications.

LinkedIn recently launched two-way integration with Twitter and also rolled out a plug-in to pull in your LinkedIn contacts within Microsoft Outlook. And today, LinkedIn is opening upits API to start letting developers make applications that tap into LinkedIn’s social network.

While LinkedIn is releasing 11 different APIs, they fall into three distinct categories. First, developers will be able to let users easily access their information, profiles, connections and messages via oAuth login. The second functionality is to give users the ability to make actionable decisions about information, but letting them message their LinkedIn contacts, post updates, accept contacts and more. And the third piece of the puzzle is search. So developers will now be able to embed LinkedIn search in other applications. The social network’s search engine was re-launched last year and has done over one billion queries in this year alone.

Over the past year, LinkedIn has made select business development partnerships with technology companies for integrations, such as IBM, Microsoft, Research In Motion, and Twitter. While these partnerships created additional channels for LinkedIn’s platform, the opening up of the social network’s API is no doubt going to expand its presence across the web, perhaps representing a new level of growth for the social network.

LinkedIn has already tested the API with several developers and applications are already going to be launching in the near future. Twitter, MySpace and Facebook client TweetDeck will be integrated with LinkedIn in its next version. From the client, you’ll be able to see a stream of updates from your contacts, view profiles of contacts and comment and message contacts directly from TweetDeck. Posterous, Box.net, and Ribbit will all launch LinkedIn integrations in the near future as well.

LinkedIn’s VP of search and platform products, Adam Nash, told me that over the past year, the network has received 4,000 requests from developers to integrate LinkedIn with their applications. Nash says that this is the first step for LinkedIn to become an open ecosystem and there are future plans for additional APIs to be released down the line.

50 million users strong, LinkedIn could expand its already powerful growth with development of third-party applications. It’s a no-brainer for LinkedIn to open up its API. As Twitter’s platform has shown, an open ecosystem produces innovative and sometimes, extremely popular, products around a product. And it doesn’t hurt to have a loyal developer community as well.
