I think it's really different. The IB presale started months before they had finished a public beta version. We didn't even see it used at vb.com yet, did we?
While XenForo seems to run pretty stable here. And I'm actually buying a product that I can already download to start developing, to start planning my migration. It's just still a beta version that is unsupported. But still ... totally different.
The first one is wrong on terms to begin with, while the second one misses the point completely. Did like the photochop job ... very very good. If continuing the biblical (Christian) analogy we need another 8 or so apostles and I'm waiting on our Judas.
And lo for a prolonged 4o days and 4o nights, we lost count there, Kier and Mike fasted in the desert of vb4 being tempted by IB ... story to continue ....
