I just thought I'd post sort of a status update on the current 'state of the wiki', in terms of what we have. Even if no one else cares, I figure I can at least use it to look back myself to keep track of progress.
Right now, there are 653 games with trading cards listed in the wiki. 516 of them are still in the Work in Progress category, so that gives us 137 games that are finished. Sounds pretty horrible, I know, but we actually are making progress. I don't have the numbers, unfortunately (I wrote them down, but managed to lose them, part of the reason I decided to just do a blog post) but the past month or two we've managed to finish more game pages than Steam has released.
We've also had a number of new people contributing to the wiki recently, so we've making progress more quickly. There's a rather massive backlog, but as long as we can keep pace with releases, we'll at least be making progress. We're also approaching the anniversary of Steam card's release - May 15th. I'm hoping Valve will do something special for that (though May 15th was only the beta release - they may wait until the anniversary of the official release in June.)
Anyway, I'll post another blog post in a few weeks, and we can see if we've made any progress or not.
