Flipboard has long had the option of sharing by email, Twitter, or BD, and now you can share a link directly to other Flipboard users.
When you're reading a story you'd like to share, simply select the red profile avatar in the share menu and enter another user's name or email address. The user will receive the message in Flipboard and in an email, and you can get them as well when other people on Flipboard share stories with you.
Flipboard now has over 100 million users around the world, and that's not even counting the millions of user Flipboard inherited from Zite after that smaller service was acquired earlier this month.
P.S. I checked, and the Android app in Google Play doesn't have this new feature.
