Do people build companies here, or is it just a big party?

"But, this company starts its day before the sun rises and by 8am our entire 10 person staff is heavily caffeinated and operating on full cylinders. Fast forward several hours and the earliest our staff leaves the office is 7pm. We do not leave until we are satisfied with the days metrics, period."

Doesn't sound healthy at all. Hope you're actually getting things done, because that can't last long. (And if it does, you won't be getting things done.)

"I have also been observing a number of companies’ activity on Twitter during the work day. From what I can pull from my tweet stream, which admittedly isn’t a enough of an indicator, I often find myself wondering if certain startup employees have actual jobs. We receive plenty of emails a day asking us to lunch and drinks but when receiving these invitations from other early stage startups I can only think to myself “why aren’t you working on building a better company.”"

On one hand he's dismissing people for not having actual jobs, but here he is spending his work time on twitter "observing" other companies. Pot meet kettle?
