I have received the email yesterday, been a Flickr user for 10 years. I had mixed feelings as I really like Flickr but at the same time how would the subscription save the company?

At the same time, I thought we they didn't put some adverts for non-Pro memebers to test if this would help to provide a new income stream which might worth more than a Pro subscription.
