There's a danger to elevate inability to communicate by phone (or face-to-face) into some kind of geek badge of honor. If you can run your business that way that's good for you but it's important to keep in mind that there are some potential clients, customers or partners that do better with phone conversations.
It's not always the inability to put things in writing or plain lazyness that makes some people pick up the phone instead of firing off an email or text. Some people's brains have an easier time developing ideas in a conversation and you may miss out on valuable opportunities if you dismiss them. You could hire or partner up with someone who likes to chat.
