I'm going as a user, not as the developer of a (future) competitor. But I feel that a product that integrates with a few forum software opens up the market by a bunch, but as a user, if I'm on vB, XF, etc., I want truly integrated. There's Tweet / Recommend buttons in XF, I want to see tweet / recommend buttons implemented. And likes, and reports, and comments, and templates.... I don't want a feature set that is global over forum software, but lacks for a specific one. I go with that on CMSes, Wikis, Portals, Galleries, blogs, etc. Integration is key!
