It had been a bit since I checked into the Grand OGL Wiki. I have to say, it looks like there's definitely been some positive movement, especially with OGL items from Mongoose.
What always got me about the idea of this product is the sheet scale of the undertaking. Consider how much OGL product has been made in the past near-decade--some good, some abysmal, but a vast amount nonetheless. I know they'll never get each and every product in there, but even getting a part of it hosted online is a big task. Let's face it--a lot of folks have stuck with some form of an OGL/d20 system. This can be a very successful resource for a good many games if it is followed through on properly.
In any case, a tip of the hat to those involved, and a thank you for their efforts. I look forward to seeing continued progress.
(Oh, and if you visit, make sure to check out this article on the PROSE system for a quick fleshing-out of NPCs. Nice take on it.).
