Brad : the practical implications are that we will lose the ability to copy work from a set of familiar collaborative sites -- many of which chose their license specifically to facilitate long-term exchange with Wikipedia -- and they will slowly lose access to the latest WP updates over months or years. (we are also gaining direct access to new sites, but that happens regardless of how we approach this hurdle) Thomas Dalton writes: Yes, wikipedia will continue to dual license for as long as this is possible. This will help GFDL-only projects dependent on Wikipedia benefit from future edits for as long as possible, but it will only last so long. Once CC-BY-SA content is merged into an article, future revisions of the article are BY-SA only. Within a couple of years, Wikipedia will be basically a BY-SA project (with a historical snapshot still available under GFDL). Third parties should not be fooled into thinking that this finesse is equivalent to being a dual-licensed project forever. If they don't switch now, they will not have the chance to do so in the future. geni writes: A quick look at the recentchanges of the 18 large wikis listed on the outreach page will show you that it's not true that "most existing stuff of relevance has long been imported" -- these are active communities, each working in their own world; which sporadically draw from Wiki[p]edia and from which we slightly more sporadically draw in return. I am surprised you (of all people :) have such faith in the horde or importers. I was looking at the glorious media and high-res source text scans at wdl.org yesterday, and could not find a single piece of that public domain media that was already on Commons and used in the obvious Wikipedia article / on its own Wikisource page. Maybe I wasn't looking in the right place... but that's a month after a global publicity blitz. On Wed, May 27, 2009 at 8:16 AM, effe iets anders <effeietsanders(a)gmail.com> wrote: Exactly. And there are some energetic new projects such as Medpedia that are just getting off the ground, with enthusiastic new authors and a constellation of supporters... they'd probably love to convert, but need someone to explain this to them in time for them to work through their own red tape.
