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)
How is it a phishing site?

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.

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.
