The US microblogging site Twitter has utterly failed to increase its number of users in the fourth quarter, he acknowledged on Wednesday, delivering forecasts in below expectations.

Twitter claiming 320 million subscribers at the end of 2015, exactly the same level as three months earlier.

Excluding subscribers receiving a Lite service by SMS, the number has even declined from 307 million to 305 million in late September late December.

This development makes it even more urgent the group’s efforts to try to simplify and modify its product to appeal to a wider audience, but the maneuver is difficult because the network may thereby alienating its current loyal users.

Twitter has also made a new attempt Wednesday by announcing a change in the presentation of the message flow seen by its users: it intends to present at the top of their message thread a personalized selection together the latest publications that are most likely the interest and they have missed. The measure has provoked considerable criticism from users.

Twitter has also said Wednesday that it was for the current quarter sales of only 595 to 610,000,000 dollars, when analysts were hoping on average so far seen up to 629 million.

Revenue climbed 58% to $ 2.2 billion over the whole of last year, and 48% to 710 million in the fourth quarter, a level in line with expectations.

Twitter, which has never reached a dollar of profit, has again posted a net loss of $ 521 million over the year and 90 million in the last three months.

In electronic trading after the close of Wall Street, Twitter share lost 2.27% to 14.60 dollars around 2200 GMT.

Investors are starting to lose patience with the network, including the growth prospects worry more.

The action keeps falling to new lows since the beginning of the year, and has lost 80% of its value since its heights in December 2013, just after the IPO.

The problems of the microblogging site seemed to intensify again recently with the mass start of a series of senior executive officers.
