NTSG, why do so many people hate on the retweetscoop?
Personally, it's not a big deal to me.
I don't want to say what others may want kept private, but I think it's probably from a similar line of thinking that caused some to be annoyed by Adam Zagoria. He was a newcomer (nationally), didn't travel to the events, and some believed he would effectively repackage others' articles or give them credit for breaking news at the end of his articles/posts (as opposed to the beginning, where all could see it). In one instance (Harrison Barnes), there was the plagiarism issue, where Rivals stepped in. The Goodman/Zagoria spat seems to have become more public, after AZ apparently became aware of Goodman talking to coaches about him behind his back.
In the case of Kline, I'd say some feel he's been sloppy with giving credit to those breaking news.
