Hi,

I put up a CC license on my blog today: www.omitneedlesswords.com. Is it 
worthwhile including that disclaimer about images (mainly from Amazon) 
that show up on my site but aren't mine? Will people know that without 
being told? Any other suggestions on my phrasing?

Also, a general question--I don't really know where a blog is on the 
continuum between a diary and a newspaper. I just plan to use it like a 
diary, and swear, express personal opinions, et cetera. Do I need to 
worry about libeling people unintentionally? Is that something a blogger 
would ever get busted for?

THanks,

Jamie
