in the end, is a new forum really needed?
Well... this is indeed debatable.
The fact that we, the older members here, will most probably not switch, that's pretty much clear. We, those who are already here, most probably don't need another forum.
But while as bitcoiners we are advocating decentralization, let's not "force" everybody in one forum, since it can easily become one central point of failure.
While other forums can never get near to what bitcointalk is, let them be.
But the fact that what OP is advertising is far from a proper forum makes it... not a good choice. Also advertising it
here won't help him.
