I love you :)
Tumblr’s mighty revenue stream opens it’s doors with a Valentine’s Day card. You can send one card to another tumblrer for free, but if you want to send more than one card, customize your picture, or send a card anonymously it’s a $1-2 fee.
I think it’s a great start and love them adding aditional features for revenue instead of simply adding more of what we are already accustomed to using for free, a typical freemium model.
