If we're going to use this page as a serious forum for discussing issues around IIIF development, it would be useful to have it as a conventional talk page, rather than a page of Flow threads. Flow is hopeless when it comes to following a discussion in sequence from the beginning, because everything is presented in most-recent-first order. It also doesn't give us the flexibility to organise and group sub-threads -- eg to group all threads discussing manifests together, or threads raising particular end-use cases. For this kind of thing, a conventional wiki talk page is more useful.
If this page can't be turned into a conventional talk page, then the talk page at eg either m:Talk:Wikimedia_Foundation_GLAM_team or c:Commons_talk:International_Image_Interoperability_Framework might be a better venue.
