Miliblogging

What would you say if you had to keep your blog post/email/whatever less than five sentences long?

You'd have the same resources - including time - to write a shorter body of text that would give the same impact.

What are the benefits to the reader? What would you have to do differently?

I've got some thoughts on this, but I'd like to hear yours first:- maybe add one or two to the end of this post as you're here, I'd be very grateful.
