The difference is pretty much all in google organic traffic. For the past two days it's up 18% and includes a wide variety of keywords going to a wide variety of pages. Kind of like it always was before panda. Referrals from google.com isn't a factor in this.
As far as changes go, I spent about an hour or two making changes back in april and have left it alone since. Cleaned up the forum and blocked it from robots, had about 20 or so pages rewritten, added plus 1 about a week ago, removed all adsense except one small block at the bottom.
What's frustrating is revenue for the site is down 70% from removing adsense but user engagement hasn't changed hardly at all. With and without adsense bounce rate is a difference of 1%, time on site is identical, pageviews are .3 difference.
