I think of it as there is a wholly different kind of relationship if you just met someone to work with, vs getting to know so that when you start-off a project what/how each contributes is clear (and the situation is known)… for ex just people, if someone sets a meeting walks in and starts talking about a project/job/invitation to something (vs having an introduction by a common known). -Some many times we see exs in media/stories, let alone all around, of someone that comes in on the fly (vs walk-in knowing about the person they are talking to, proposal in hand that is relevant to short and long-term interests of both parties… how know how to do that? contact)
slightly off-topic but seems to illuminate: an ex of a Venture-Capital firm that doesn’t take “drop-ins” nor post their phone#, even their website is a few pages of summary, but the “contact” says that they only communicate with those that come recommended via a previous client of their’s
(i.e. no submissions by email; common understanding is that can't be how a biz works, you have to put your-self out there... but in the "common understanding" (~contrarion) the idea is to base a relationship on supposition of the usual, mixed with each new you have to explain how you do things, negotiate of the way to operate/ explain we-do this/we-don't do that, etc... Different ways) relevance to this: mutual selection process of elimination (and/or referral to else?) prior to working? or just so and so= application, all comes down to Contact.
