I am not sure how you read my post on public data.
People upload favorite media to SAFE. Other link to it in facebook, or whatever and others see media when visit those social networks, or follow links in the social network sites, private web pages, or whatever.
Then from there the interest hopefully grows because smart uploaders store their media safely on SAFE and the masses get used to their media coming from there. ALL without the uploaders/masses needing one extra line of code (PHP, RAILS, ORACLE SQL, mySQL, or whatever)
No barrier for the masses to start consuming SAFE data, no need for APPs to be “good” enough for SAFE to be used. Obviously if it remains that way forever then that is a problem, but as we saw with the current internet, it took a decade before things really took off. It will take a little while for APPs to take off. But if no one uses SAFE then the fuel/desire for SAFE APPs will perhaps be too low for them to reach critical mass.
