Twitter's share price fell by almost a quarter last night, after leaked figures showed its quarterly revenue had failed to meet investors' expectations.
The tech giant reported weaker than expected demand for its new advertising system, while user growth was slow in April, leading to a drop in value of up to 24%.
Wall Street had expected revenue of around $2.3bn (£1.5bn) in 2015, but estimates have now been reduced to around £2.2bn (£1.3bn).
Meanwhile, Twitter's chief executive Dick Costolo has suggested that users might begin to see "curated" feeds of noteworthy tweets. Rather than the unfiltered chronological stream of updates Twitter users see at the moment, in future they might end up with a Facebook-style algorithm, which picks and chooses what its users see.
Twitter has unveiled a change in its policies to expand the site's powers to deal with abusive behaviour.Read the full story ›
Ed Miliband was the leader with the most mentions on social media during the challengers' debate tonight.
Although the Labour leader topped the mentions, there was no detail yet on how many of them were positive or negative.
According to Twitter the rank of most mentioned on using the #BBCDebate was:

- 2. @NicolaSturgeon
- 3. @Nigel_Farage
- 4. @natalieben

Turkey has blocked access to Twitter and YouTube over the publication of photographs of an Istanbul prosecutor held at gunpoint by far-left militants hours before he was killed in a shootout last week, officials said.
Presidential spokesman Ibrahim Kalin said a prosecutor had sought the block on access to social media sites because some media organizations had acted "as if they were spreading terrorist propaganda" in sharing the images.
This has to do with the publishing of the prosecutor's picture. What happened in the aftermath (of the prosecutor's killing) is as grim as the incident itself.
The demand from the prosecutor's office is that this image not be used anywhere in electronic platforms.
Istanbul prosecutor Mehmet Selim Kiraz died from his wounds last Tuesday after security forces stormed the office where members of the far-left Revolutionary People's Liberation Party-Front (DHKP-C) had taken him hostage.
The DHKP-C had published a picture of Kiraz with a gun to his head and said it would kill him unless its demands were met.
"A request has been made to both Twitter and YouTube for the removal of the images and posts but they have not accepted it and no response has been given. That's why this decision has been taken through a court in Istanbul," a senior Turkish official told Reuters.
Twitter and YouTube could not immediately be reached for comment.

A Twitter user who was investigated by police after posting a "joke" message saying that he had driven off after hitting a cyclist has been sacked from his job at a major fund broker.
Writing under the account name Ray Pew, Rayhan Qadar tweeted yesterday: "Think I just hit a cyclist. But I'm late for work so had to drive off lol."
The 21-year-old, who later retracted the tweet and apologised online, told reporters it was a "a made up thing" and "a joke gone bad," The Bristol Post reported.
"I am 100 per cent sorry," the former Cardiff University student said.
But the apology was not sufficient to save his job at Bristol-based Hargreaves Lansdown.
One of our employees has failed to conduct themselves to the standards we expect of our staff. We find these online comments totally unacceptable.
Upon becoming aware of this issue we have terminated this person's employment with immediate effect.
