> Instead they should have tried to identify a niche where Facebook was failing (say, intimate private sharing, or the antithesis of the narcissist fest) and build up a loyal core of rabidly passionate users, then slowly expanded from there. Great advice for a YC startup, but not how big companies that already have large user bases operate. Big companies have a metric they want to drive, then look for big opportunities, simply because dominating a “niche” is too small an opportunity to make a dent in a big-company metric like DAU, time spent, etc. If you do want to start with a niche, it can be super hard to justify continued investment from management, given that there are so many other bets that can drive larger near-term changes to metrics.
