The latest person to get into trouble over his blogging is none other than CNN talk show host Larry King. King keeps a blog on the CNN Web site, even though a couple of years ago he said that he never goes on the Internet at all.
Now, blogs borrow material from other sites all the time, but it is considered kosher to always provide an attribution. Larry (or someone calling himself Larry) apparently has been putting up posts from other sites without any indication that it came from anywhere else. That's a no-no.
Everyone realizes that everything on the Internet is linked to everything else. There's no problem with that. But if you do, give credit where credit is due.
