Caldwell was hugely instrumental in growing the site from a couple of employees to over 200 worldwide people, and built out one of the best tourney reporting crews in the business. Additionally, under Caldwell the site became a SEO monster that is currently translated in numerous languages, because apparently not everyone speaks English.
Says Caldwell in a statement on poker news reporting site PokerNews.com:
"I just felt it was time…I'm looking to change focus, and now felt right. It was, quite simply, time to go. I'm really proud of what we accomplished at PokerNews. In a matter of a little over three years, we went from three guys in a tiny room to one of the largest poker sites on the web. PokerNews will always be a chapter in the book of my life that I am proud of. I have really enjoyed working with PokerNews. I'll continue to contribute as a consultant on an ad hoc basis. I wish Tony, Damon, and everyone at PokerNews continued success"
So yeah, unfortunately no salacious details people. Read more here.
