People will pay for Flickr Pro accounts (Flickr was profitable due to this). People aren&#x27;t going to pay for Tumblr.<p>EDIT: I&#x27;ve previously said on HN that I&#x27;d like to buy Flickr and roll it into a benefit corp&#x2F;non-profit sort of deal. I firmly believe that Pro users can pay enough that Flickr can self-sustain itself.
