"I met people through Twitter whom I wouldn't have otherwise. Readers sent me story tips over direct ..." — Maggie Haberman

I wasn't always a Twitter devotee. During the 2012 campaign, the first during which Twitter was widely used by journalists and campaign aides, I became something of a scold to younger reporters who I thought misused the medium.

Twitter has stopped being a place where I could learn things I didn't know, glean information that was free from errors about a breaking news story or engage in a discussion and be reasonably confident that people's criticisms were in good faith.

I have a running conversation with a couple of colleagues. Mike Schmidt's one of them; some on my White House team are others; Alex Burns on the politics team is another. That just helps me not lose my place, right? We're just constantly talking about what we're hearing and where things are.

When somebody is describing their job as fixing problems for someone, that usually does not suggest that they're dealing with their tax returns.
