Latin meaning: "what now?"
English meaning: a person who seeks to know all the latest news or gossip : busybody
What's more is that the vagueness of this news has turned a lot of us into quidnunc scavengers, rummaging around the internet looking at profiles and website source code like fake tech sites scouring artists' portfolios for 3D iPhone mock-ups to report as "news".

In Latin, quid nunc was a question more or less equivalent to our conversational "what's new?" or "what's going on?" A person asking that question a little too frequently might be accused of intruding on other people's business. Perhaps that's how Sir Richard Steele, in 1709, came to use quidnunc to mean "a busybody or gossiper" in The Tatler, his influential British journal of society, gossip, and manners.
