No, no, NO! We have enough whackjobs here as it is, do you really want to let every yahoo with a Facebook page in? As for "integration," in my experience that works out to "sitting and waiting for the page to finish loading while a choked-up Facebook CDN/Google Analytics server struggles to provide a 'Like' button graphic/who the hell even knows." That's the last thing we need.
Agreed. Facebook integration is just annoying to say it in the most polite way possible. I wouldn't want to crawl other users face book page anyway, and I'm sure nobody wants to crawl mine either. It's a place where I keep up with grandma and post pictures of my cat!
