It is not just ground breaking news like Black Friday where poker news sites are readily linking to each other. I mentioned yesterday that 'News In Brief' features are seeing this happen every day, and often on much more whimsical stories.
Ultimately poker media sites do not want to out of the loop with any stories that are taking place in poker. We have got to the point where we have realised that rather than pushing our traffic away, never to be seen again. If we provide a good enough source of news and/or affiliate deals, the audience will keep coming back for more.
It also shows, in my opinion, a great deal of integrity that we are prepared to take such a risk in the name of good news reporting, and I think the audience get that.
Of course, the absolute worse thing you can do is still carry the story, without giving proper citations. Although the typical reader probably wont notice, your peers in the poker media will, and expect a cold war on twitter and snubbing at WSOP and PokerStars parties forever more.
