Meetings I have with my friends are either planned over email, or via something that is specifically designed to pick a date, like <a href="http:&#x2F;&#x2F;doodle.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;doodle.com&#x2F;</a>.<p>The network effect works both ways, I was one of the few people initially who didn&#x27;t adopt facebook, so anything that involved me had to be communicated over mail.
