Here's the quote
Why should you be excited?
This is a potential game-changing development, possibly at a par with Gmail’s launch. Gmail, apart from its matchless usability, is after all just another web-based e-mail service. If Facebook (FB) e-mail lets me import contacts from FB — keeping the hierarchy of contacts intact — it is a huge thing. People could use FB e-mail exclusively for their social network.
