Just because I like to back things up with numbers, here's some
1 - people that arrived at the site after searching the word "greenguy" went from a bounce rate of 18% to 10%
2 - top 3 hard link traffic sources bounce rates went from:
A - 31% to 23%
B - 30% to 23%
C - 16% to 11%
3 - main page info:
A - bounce rate went from 33% to 21%
B - page views increased 34%
C - Avg time on site increased 20%
Based on those numbers alone, I think the new design for the index & main pages are a great success
