Seriously guys Tichy has a point here. I am a big fan of YC startups ( even though we did not make it this time and sure will next one), but telling us about the night before and the day after is not really "feeding one's intellectual curiosity". So please let's try to stay around The "Hacker News" theme until we change it to something broader.
PS:"Matt, this is not personal at all. We just want to know what's for diner"
Put yourself in their shoes. If you had a choice between making people happy on a web forum and doing what you think is best for your StartUp, which would you choose?
There are cases where StealthMode makes sense, right? Without knowing what they're doing, it'd be hard to give a good reason why they shouldn't be in StealthMode.
