This feature sounds great on paper. But it means adding yet another FB dependency (or third-party if you will) to my web page, and that means more stuff for users to download. It also clutters the UI and placing it on a page can sometimes be a mayor PITA, depending on the layout of your page, and the last thing I want is to redesign parts of my pages yet again because FB released a new button. You can always choose not to use it, but we all know how that is with search-driven traffic. Now days if you don't have FB's like button it's like putting "Disallow: *" in your robots.txt. And it will (probably) be the same with this "send" button. I just wish they'd figured out a way to combine the two.
