Ehhh, when so little is offered Free, I disqualify the word.
Very good interview with Will. The confusing thing about IMVU though, is that he says its not a virtual world, yet many of the aspects of IMVU, such as economy, come for a virtual world, little if ANY other IM Add-Ons have an economy system. I also find most of the avatar models ugly, big heads and little bodys remind me of sick etheopian(sp) children, or aliens. However the avatar technology is of course great, I believe most of the ideas come from what they did at There, so it's really just a continuation of that feature.
As for a question, if you'd be willing to ask him, since IMVU makes such use of Open Source tech, would IMVU ever go full open source? Or what parts of it would they open? Also he said they had already made contributions, where? And What?
With regards to some of the other information I've learned in this thread, I was planning to discuss the user creation and economy with Will next round, so it's good to know some of the background issues beforehand. Learning that IMVU has been breaking user creations with new versions of the software is useful (thanks, Veritas for the tip).
