I love that idea. As an occasional angel investor, I actually use a variation of that filter as well. Out of politeness, entrepreneurs will offer to have a call with me to talk me through their business. I tell them no call is necessary, they have better things to do with their time. If someone insists on a phone call without at least trying to see if we can accomplish what's needed over email, it's a no go for me. Thankfully, just about every early-stage entrepreneur I've encountered has no issues with this approach. They prefer it.
