RTE presenter Miriam O'Callaghan admits that Twitter can be "lethal" and must be used in moderation – but insisted she will continue to tweet.
Her comments come after staff at the national broadcaster were asked to sign off on new guidelines regarding their use of social media.
The Irish Independent last week revealed how the publication of the report on 'The Frontline' presidential debate prompted an updating of guidelines, with new training sessions on social media planned for staff in the new year.
Insiders at the station claim that staff have been advised not to tweet while in RTE unless it directly relates to the contents of the programmes they are working on.
With more than 50,000 followers, presenter Miriam O'Callaghan is a big fan of Twitter.
Speaking in Limerick, where she hosted the National Children of Courage awards with 2FM DJ Will Leahy, the mother of eight insisted Twitter "is a very good medium".
"I tweet the way I always tweeted actually, like boring pictures of a chocolate cake I've cooked at home. I primarily tweet about things I'm doing. I will tweet tonight about this," she said.
"You have to be careful obviously, it's lethal. You are broadcasting to the universe and once you know that and once you cop on to that, it's still a very good medium.
"I can put something out today and someone in any part of the world could see it. So it's positive and it's also incredibly useful.
"But like everything in life, just be careful with it and use it in moderation."
The 'Prime Time' presenter is confident RTE will become a stronger and better organisation following its recent difficulties.
"I love the place, I love the people there," she said.
"It's a great organisation; everything in life has its ups and downs. We had serious problems. We have dealt with them. We will go forward and we will be stronger and better."
