I can't say I'm not kind of curious to see this too. None of the sites I frequently regularly use IPS, so I've only had very limited real experience with it on their official forum.In all seriousness...
I was only being a little snarky.
Cumulatively, TAZ has unprecedented knowledge, skill & resources that cannot be matched in the forum world.
TAZ is good on XF with and the cornucopia of addons its using.
But I'd LOVE to see TAZ use Invision Community and it's addons. Robust social features. All the interviews and articles in some well developed Pages. A first party Blog platform. Commerce for upgrades and Advertisement sales. And much more.
It'd be great to see, really, but a huge commitment of resources.
