Agree - but don't think there is a "best mind(s)". We're creatures of repetition and thus specialization, and so our minds can get really good at very specific things, but ultimately we're all dumb apes trying to survive as best we can.
Is this person trying to dump FB stock for his own benefit? It makes me very skeptic that he had to tweet 11 times in a very alarmist tone. If his opinion is firm on transitioning from FB to a more private and secure alternative why not just say that in 1 or 2 tweets in a tone endorsing other platforms perhaps in a more positive manner?
Scribd: We don't expect to compete with Scribd. We think there is a lot of space to find a different niche, but in order to get to that we basically need to tread a very similar path as Scribd's.
Language: The website is translated automatically for all Latin American Countries and defaults to english for the rest of the world. The only difference is, when you're browsing in english, you only get english documents and when you're browsing in spanish you get both spanish and english documents.
Legal: The way we're approaching the legal situation is by removing any document that is reported and requesting appropriate proof of the copyright claim.
Spam: We fight spam by allowing the users themselves to moderate the content, much like medium or even hacker news itself.
Startup Chile: As far as Startup Chile goes, we haven't thought of going there. Have you been there yourself? Any hints or advice you could share with us? :)
I respect your opinion. However, I'm the type of person that fuels from relationships. Regardless of the complications, the added motivation and state of mind in general I get is well worth the cost.
