Has Twitter become too toxic for its users, or is it still an important tool for social cohesion?
Philip Nolan, columnist with the Irish Daily Mail, says: "Rage is one of the predominant emotions I see there nowadays, and it has in some ways facilitated the resurgence of the alt-right. It's become more polarised than it was in the early days."
"I love it because I get to see views I wouldn't necessarily be exposed to, but at the bottom of it all there is a lot of rage and anger and it's expressed very poorly occasionally."
Aoife Barry, deputy news editor with thejournal.ie, points out that "there are about 319 million active users on Twitter at the moment, so that means you're going to have people you don't agree with."
"Twitter is a microcosm of the world as we know it and you're going to have the positive and negative sides."
Aoife says that those working in news and current affairs can't really afford not to have anything to do with Twitter.
"Twitter has some serious issues, but it's helpful too."
