If you're going to monologue, I'll take a blog post over a speech any day. But if we need to work out details, let's get conference chairs. If we're planning a party, online will do. Once we're hanging out, we'd better be in the same room.

So long as you get out enough, I think this is fine. When you're doing something rational, online written communication is great--you omit all those distracting interpersonal protocols and focus on the issue at hand.
