Twitter sets new record of 1.96 billion tweets a month

Popularity of the social networking site has been increasingly growing in the United States, UK and Japan, while also getting global reach faster.

On Monday, Twitter said it plans to hire its first employee in Washington DC to act as a liaison between the site and the White House to manage its relations with the White House.

The company said it wants to hire someone who is the closest point of contact with a host of important organizations and people who are looking to get the most out of Twitter on both strategic and highly tactical levels.

The job advertisement had said the "liaison figure" will help Twitter to understand what it can do “to better serve candidates and policymakers across party and geographical lines”.

The employee will also support policymakers' use of Twitter to help them "communicate and interact with their constituents and the world", the ad said.

Currently, all the Twitter's employees are based in San Francisco. Costolo said Twitter plans to open offices in Los Angeles and New York and later in the UK and Japan.

Recently in May, Twitter had said it would not allow third-party ad networks to use the company's API (application programming interface) to include paid tweets in the Twitter timeline.

The company said its own promoted tweets ad service will remain, allowing companies and others to place messages of up to 140 characters atop a search page.

In a blog post, Dick Costolo wrote, "It is critical that the core experience of real-time introductions and information is protected for the user and with an eye toward long-term success for all advertisers, users and the Twitter ecosystem.”

Costolo also said that Twitter would start charging companies that sell advertising around Twitter content.

Companies such as Ad.ly, a US firm that sells ads in to Twitter streams, and Tweetup may have to look elsewhere, for this revenue, reports say.

Costolo said such companies could continue to sell analytics and other services based around Twitter.

Twitter said it would be issuing revised terms of service to outline more clearly what will and will not be allowed under this rule change.
