I don't know precisely where you live in the US, but that's not my experience of coders in the UK, or indeed many places elsewhere.
Even (especially?) in the open source world, people generally don't like coders that go it alone, or are resistant to feedback. It only causes problems later, especially if their component becomes important.
There's plenty of opportunity for coders to socialise, and work together, and it occurs regularly.
