I certainly don't consider myself much of a hacker, and I don't think many here are either.
We are programmers. We build stuff. We need to know everything there is to know about security risks, but most of us stopped coding windows trojans and worms after high school.
I don't think many of us know (or care) how to write keygens and cracks for games, or invisibly extract cash from a bank via social engineering.
That's the definition I subscribe to. Hackers are highly specialized in computer security, whether they're white-hat or black-hat.
So Reuters is not using the wrong definition. It just feels like school kids giving new meanings to words, then laughing at their 'lame' parents who don't understand.
"Tinkering" sounds kind of lame, but it is what it is.
EDIT: Oh yeah, I'm posting on Hacker News! The new meaning is fine, but don't act like other people are stupid for not getting it.
