Ummm... This is a forum for people interested in startups, which are defined more as "start fresh, then use it to burn down the old thing." Not exactly the same thing, but offend driven by the same sentiment.
What works at a startup often can't work at a big company. Or a university. Or a government. You have to work with the system you have. For those that leave angellist without a second thought, what are your alternatives? LinkedIn?
