There is currently no good way to get your friends email addresses out of facebook. The emails are displayed as pictures meaning you can't cut and paste. There are programs that will scrape the data but these will get you banned for abuse. I know facebook wants to keep you on the site all day but i want to communicate with my friends outside of facebook too. Facebook messages just don't compare and are slightly clunky to boot. If they really wanted to connect us with our friends, they need to make it easy to export email addresses.
