Whereas in the UK we loved David Whitehouse’s sarcastic comment about cycling cheat Lance Armstrong. It has subsequently been retweeted more than 10,000 times.

But for most brands, it probably wouldn’t pay off if they were constantly trying to entertain – though there are some notable exceptions in the form of Arena Flowers and Betfair Poker.

Instead, Daisley suggests that the approach should be to blend one part humour with three parts seriousness.

The challenge for any brand is thinking about how they can establish a friendly relationship with people. They need to provide value and substance but with a human tone.

This is a tightrope skilfully walked by the likes of ASOS and Tesco, which we recently analysed in a look at how the top five UK retailers use Twitter.

O2 also hits the right balance, deftly dealing with customer queries and complaints with a mixture of politeness and humour.

Specsavers is another great example of a brand that has used humour in its marketing, as well as taking advantage of Twitter to react in real time to the day’s events.

Back in January Chelsea footballer Eden Hazard was banned after kicking a ballboy at the side of the pitch.

Specsavers immediately responded with this advert, which has gained more than 3,000 retweets and is still pinned to the top of its Twitter feed.

Daisley’s final example was a funny riposte from the Lib Dem press office in response to an attempted jibe from the Labour press team.

It shows that impact that humour can have in bringing a more rounded, human image to an otherwise dry Twitter feed.
