From there, I think the debate will turn into whether employees at one DFS site should be allowed to play on other sites (actually, that debates already on).
I, for one, think they should be able to. It gives employees the opportunity to experience what it's like to be a user of a similar product. It lets them stay up to date on their competition. And I just think it keeps people inspired. If you really like this stuff - enough that you want to work at a company that makes it - I think it's motivating to experience that when you can't use your own product due to its nature.
However, I'm pretty sure I'm in the minority. I think I actually saw that FD and DK have already banned their employees (in the wake of this) from playing on each others sites.
But to me.. that's silly. If you make it impossible for employees at DK to have access to the data ahead of time and vice versa, then there's really no unfair advantage. Plus, if their products weren't the exact same (and products in this industry WILL diverge), then it also wouldn't matter.
