One of the lowest points of Miriam O'Callaghan's experience with social media came in 2011. Following her interview with Sinn Féin leader and Presidential candidate Martin McGuinness, the Prime Time presenter received death threats via Twitter following the broadcast.

"I understand that Twitter can be a cruel and nasty place but I'm still on it" she told Donal O’Donoghue of the RTÉ Guide. With a positive outlook, she refuses to be intimidated on Twitter or anywhere.

"Maybe because I'm a bit of a toughie and I don't want to be driven off a platform that is very useful to my job. If you treat people with great politeness they normally respond in kind.”

Her motto, which she uses in the context of Twitter, has always been: “If you treat people with great politeness they normally respond in kind.”

And it seems Miriam is in no fear of stopping her social media presence anytime soon. Recently she took over Snapchat star James Kavanagh’s account, something she described as "so much fun". 

Miriam took over James Kavanagh's Snapchat as an experiment for Saturday Night with Miriam:

Could Social Media be Affecting Your Life?

But in recent days, the argument of social media and it's purpose has reigned heavily in the media. On the Claire Bryne Live show the issue of children using social media was hotly debated.

Couple that with recent legislation which allows people to be prosecuted for negative online activity, where do Miriam's views lie now?

Speaking to the Irish Independent at the launch of Trick or Treat for Temple Street yesterday, she admitted the playing field has changed: “By and large people are very nice. People realise they can be prosecuted for what they say now.

“I don’t go on the hashtag #MiriamOCallaghan until two days after the show has aired. By then all of the nasty comments have gone, and I don’t want to see them"

Miriam recognised that young girls in particular can feel very pressured using social media these days:

“Sometimes they judge their popularity by how many followers or likes they have. Or what their friends say. I tell my girls that the real world is the right place to be. If people are nasty, try to deal with them politely."

"If that doesn’t work, just forget them,” she added.
