If prostitution were legalized then it could be regulated making it more likely that proper healthcare and protection is administered. It also gives a prostitute the ability to report to the police if there is foul play without worrying about getting in trouble for the prostitution itself. Much like the war on drugs, trying to eliminate prostitution by criminalizing it is not an effective way of eliminating the problem (if you see it as a problem).
I actually think that could be a decent way to balance the fact that people don't want to see ads with the fact that FB has to have ads in order to make money. As long as they did it in a way that didn't disrupt the user experience too much
I agree. Many founders spend much of their time networking in order to gain early users. Not all of this time can/should be eliminated, but if founders can be more efficient in gaining initial users that is a good thing.
That's the nature of startups. Most don't succeed. I don't think YC would make a claim that they are some automatic path to success, just that they help good ideas to get there
