The Lib Dem surge online
Another week, another digital news cycle - and this time it's one dominated by the sudden rise of Nick Clegg's Liberal Democrats.
For our Daily Politics piece this Monday I've looked at the reaction online to Mr Clegg's performance in last week's prime ministerial debate.
The debate itself has proved a YouTube hit for ITV, with almost 134,000 views for the 90-minute clip and thousands more for shorter clips.
For a shorter interpretation of the debate you can try this 15-second cartoon summary.
Elsewhere, almost 100,000 have now joined a Facebook group with the aim of getting the Liberal Democrats into office, while supporters of Nick Clegg have started an online shop selling "I Agree with Nick" merchandise.
Google search data is also interesting: the Lib Dem leader is by far the most searched-for leader in the days since Thursday's debate.
On Twitter and in the blogs the Conservatives have been hitting back. A Conservative press officer Henry Macrory was quick to spot a letter describing a Clegg as "a horsefly - a nuisance but hardly a major threat".
Meanwhile the ConservativeHome blog has been filling up with inventive posters created by its readers to question Lib Dem policies. And Tory blogger Iain Dale has been warning that personal attacks on Nick Clegg could backfire.
Labour has been rather quiet online, so quiet that it was not until after our report was finished that we found something new from them, this quite inventive site portraying a grim economic future under a Conservative government that was launched at the party's morning news conference.
But the most pressing question to emerge over the weekend was about this video by the Cameron Girls: genuine Conservative fans or a cheeky Labour or Lib Dem viral?
