I don't know if this question really has an answer, but it's been bugging me for a while: When did it become fashionable to start sentences with the word "which"?
Here's a short example:
I drove straight home after work. Which means I didn't stop for groceries.
These two sentences could easily be combined into one sentence with a comma between them.
Here's a longer example that seems to occur in almost every magazine article:
The president on Wednesday ordered a massive bomb strike against the rebel stronghold in an attempt to drive them out of hiding, killing hundreds and creating protests around the world. Which won't look good in the November election.
Are writers trying to be fancy? Is this a new writing style that's being taught?
