As I said in my other comment I don't think this is really comparable to founders of a startup. Techcrunch50 may be a separate new corporation (I don't know), but it's really just a product of an existing company. This is like a consultant and a founder parting ways.
Clearly you dont know. Somehow "ErrantX" was able to get the jist. But you seem to have missed it. Regardless of what kind of company it is really. New, old, startup, whatever. The extremely simple point here is that feuding destroys working relationships, no matter what way you choose cut it. And PG says this in his article, in black and white That this is what he dislkes the most about startups. And therefore the two are related. Who cares what stage the company is in. If it is a partnership or whatever. The notion applies to all. You missed the point. Read the article.
