BBC political correspondent Chris Mason is finding time between bulletins to answer questions posed on his Facebook Q&A, external . Katy Eloise, politics editor at Nouse - the University of York's student newspaper - asked: "Do you think Sturgeonmania will last or will it subside like Cleggmania?"

Here's Chris's reply:

Our correspondent continues: "The funny thing with Cleggmania is the party actually LOST seats at the 2010 general election. But what we don't know is whether they would have lost more without it or whether the mania had simply fizzled out by polling day."

Former SNP leader Alex Salmond was clearly impressed with his successor's performance last night, as he proved while campaigning in Kirkcaldy.

BBC North America reporter Anthony Zurcher has been in the UK to describe the British election campaign for the audience in the States. And he reckons last night's fare was "much more interesting" than is served up across the pond.

The writer imagines a reworked 2012 debate between Democrat Barack Obama and Republican Mitt Romney - with the addition of "conservative populist firebrand Pat Buchanan, Libertarian Ron Paul, a Green Party candidate and pro-independence nationalists from Texas and New England".

This endless talk of policies, polling and possible coalitions is taking its toll on the commentators. This request from a BBC News Channel producer found its way to Election Live team a short while ago:

More on that Survation poll. It gives Labour leader Ed Miliband his first ever net positive approval rating, meaning more people approve of the way he's been doing his job than disapprove.

It's "rocketed" to 4.4%, says the Mirror - although that's still a way behind David Cameron (7.7%).

The SNP's Nicola Sturgeon surged 19 points since to 15.4%, placing her as the most popular leader, followed by Plaid Cymru's Leanne Wood. Despite a decent increase in support, Nick Clegg is still in negative territory as the least popular party chief. Nigel Farage is placed fourth, behind David Cameron.

A Survation poll for the Daily Mirror puts Labour two points in front of the Conservatives. That's the same result as its last survey, a week ago. The only shift is that UKIP has gained one percentage point, rising to 18%, at the expense of the Greens (3%). The poll places the Lib Dems fourth (9%), with the SNP on 5%.

Asked about the importance of TV debates, Prof Larry Sabato of the University of Virginia, tells the BBC News Channel they help galvanise the core vote but that last night's televised event probably made little difference to the election. "Most people tune into a debate to root for their sides," he says.

Former Labour cabinet minister Margaret Beckett says an Ed Miliband government would pass legislation to give 16 and 17-year-olds the vote. Meanwhile, the Conservatives' Justice Minister Chris Grayling says he expects a debate on this issue in the new parliament.

That won't please UKIP. A couple of days ago, the party's economic spokesman, Patrick O'Flynn, was arguing that people aged 16 and 17 shouldn't be allowed to vote in any referendum on EU membership because they had been "brainwashed" by pro-Brussels propaganda, external at school.

Comedian Eddie Izzard is wearing out some impressive shoe leather campaigning for Labour. He's in the Black Country today, wearing bright red lipstick, a black pencil skirt and black high heels that would do Theresa May proud.

He's criticised UKIP leader Nigel Farage's aim of leaving the EU. "Running and hiding from Europe is not going to change anything," he says.

George Formby would not be impressed.

The Electoral Commission has ruled that a Devon man who planned to stand for election under the banner of the Ukulele Independence Party cannot use the name.

It could too easily be confused with that of Nigel Farage's United Kingdom Independence Party, the watchdog ruled.

Kevin Tyrrell's manifesto would have included free ukuleles for hospital patients and a new bank holiday to celebrate Formby's birth, according to the Western Morning News, external.

Here's the sort of picture you're not too likely to see during this election campaign.

That's former PM Tony Blair being led under an "exit" sign at Labour's 2005 party conference. But the BBC's Callum May describes how party spin doctors have been covering up these pesky illuminated menaces to foil attempts to snap embarrassing photographs of party leaders.

The Association of Chief Fire Officers is unimpressed, however. A spokesman complained: "It puts people at risk of getting trapped or lost if a fire breaks out."

Fashion magazine Cosmopolitan has been getting to the heart of what matters in this election: politicians' favourite hangover cures.

Conservative cabinet minister Nicky Morgan plumped for a trusty bacon sandwich which, perhaps unsurprisingly, wasn't the first choice of Labour leader Ed Miliband. It's been a while since he's had a hangover, apparently, but his fail safe is "drinking lots of water".

And what about Nick Clegg? "Three young boys running around usually does the trick." Hmm, not sure we'd agree. Green Party leader Natalie Bennett's go-to sounds great, if a little hard work: "Home-baked gluten-free bread with butter and honey."

So there you have it.

The BBC's Ben Geoghegan has been reading into the body language at the end of the debate, and he reckons David Cameron wasn't too impressed with his Lib Dem deputy.

"The handshake between the prime minister and Nick Clegg was a little bit perfunctory, a little bit frosty," he says.

Commentators are still scoring the debate. Alex Deane, former speechwriter for David Cameron, offers his view via the Real Clear World blog, external . Unsurprisingly, perhaps, he reckons his old boss top-scored with 8/10, alongside Nicola Sturgeon.

Deane had Miliband and Farage level on 7/10, and the three others on 5/10. But, pointing to polls suggesting a 50-50 split when respondents were asked who had performed best between Mr Cameron and Mr Miliband, he says there's plenty of life in the campaign yet.

Nigel Farage's comment during the leaders' debate about migrants using the NHS for HIV treatment at a cost of £25,000 a year per patient provoked plenty of reaction. It was the most tweeted about comment of the entire debate, according to BBC social media editor Chris Hamilton.

Now Dr Rosemary Gillespie, of HIV charity the Terrence Higgins Trust, has chipped in , saying: "HIV doesn't discriminate and politicians shouldn't either".

Political junkies who fancy a break from all this talk of election debates could do worse than check out a new play about Geoffrey Howe - the mild-mannered minister who toppled Margaret Thatcher with a deadly resignation speech. Thatcher is played by Steve Nellon (pictured), who you may remember as one of the voices of Spitting Image.

It's "a love letter to old-style politics," playwright Jonathan Maitland," tells the BBC's Brian Wheeler, "where being rubbish on TV didn't matter."

Dead Sheep is at the Park Theatre, in Finsbury Park, North London, until 9 May.
