I would imagine most of these investments will go to three places: * Sales - start generating revenue from all these eyeballs, leveraging your interest graph for targeting. this requires way more headcount than you'd expect, especially to chase enough revenue to justify a $10b valuation * Safety - beyond all the well-discussed dangers of large-scale user forums, this also impacts monetization. you don't want to subject the average new user to extreme/alt/adult content (though you can still offer space for those communities) or else you may scare them off. major advertisers want "brand safety" and want to avoid being associated with upsetting or even mildly profane content * Regulatory - dozens of countries and states are rolling out unique regulations around privacy, data usage, and user rights. this is a nightmare to navigate from both a product and legal sense
