Are we getting close? I'm pretty excited about 4.0? Any target date?
I get dinged by Google for page speed (they call me out in Adsense, Webmaster & Analytics) and it is really due to Tubepress. Don't worry, I also get good scores for content BECAUSE of Tubepress.
But with your 10-20x improvements looming large, this should be a significant improvement across my site. I have about 35K pages and almost every single one of those pages has a gallery. Yes, 35K galleries.
So you can see why I'm super excited!
