I think bitcoin.com is a pishing site.
If you write bitcoin.com, it will be changed to bitcoin.org(at least happened in the past)

It's owned by Roger Ver. it's pretty much the same as this forum, but a lot more quiet 
I tried to sign up a few times, but it never once sent me the confirmation email.
I signed up, and it worked fine for me.
A lot less traffic than bitcointalk which is to be expected since it's new. But in the longrun I think it will become more popular, since it is bitcoin.com. This is where newbies will flock to, I'm speculating.
Don't think that forum will last very long, especially once they stop rewarding people for the best thread/post. It's basically like advertising since these rewards have the purpose of attracting people.
