Agreed 100%. A lot of current features from vb2 to 3, and IP1 to 2, started as mods on vbulletin.org. A similar resource for IP.Board would probably attract a lot more developers. It's not just a list of mods, it's a community that inspires developers to interact, roll up their sleeves, and create.
I haven't taken a look at IP.Content yet, but the way it's described, it looks like the perfect platform for developers to really use their imaginations. A lot of people want an "out the box CMS," but Invision seems like they're thinking way beyond that. Now they just need to capitalize on the idea. I predict a record number of vbulletin owners switching to IP this year, and it'd be great to steal a few coders too. :whistle:
