Alight guys … i was not there … i wish if i was there .. may be some other time .. but here are some Takeaway points from SMX Advanced …
1.) How the Engines Handle rel=”nofollow” Links
Google engineer Evan Roseman clearly outlined how Google deals with links that have the rel=nofollow tag. First, he said using the tag isn’t a red flag to Google. Second, he explained that Google won’t use such links to discover new pages. “We act like the link isn’t there,” he said. (Note: Fellow search marketers have done experiments that suggest this isn’t true.)
Yahoo’s Priyank Garg said that Yahoo will crawl nofollowed links to discover new pages, but that they don’t allow the links to pass any credit/authority to the page being linked to.
After some confusion, Microsoft’s Nathan Buggia said that Live Search doesn’t use nofollowed links to discover new pages.
My View: Engines do crawl nofollow links to discover new pages. Engines do give them credits.

2.) Matt Cutts Comment: “The original PageRank was purely a page-level document.”
That doesn’t sound too interesting on its own, but this thought occurred to me: When he says that PR was originally a page-level thing, is Matt suggesting that Google now uses some kind of site-wide PR score, too?
3.) Matt Cutts comment: “We work very hard to make sure you can’t hurt a competitor by buying links to their site.”
You CAN hurt a competitor by buying links to their site, but we work hard to make sure that doesn’t happen.
4.) About Page Rank.
During the Analytics Every SEO Ought to Know session, Jonah Stein made an interesting analogy: “Crawl frequency is the new PageRank.” I’m in favor of this as PR is like TrustRank for a site for visitor+spiders … The more a search spider hits your site, the better you’re probably doing at giving it what it wants: good content.
5.) All Links to a Domain Help Every Page on that Domain Rank Better
Thats what i marked till now … will update this post when i will find some other interesting points !!
