Here’s another worthwhile Techcrunch post, this time about how Twitter gets the Audience idea right. The post is by Gregor Hochmuth.

I have my own ideas about why Twitter works, but I’ll save them for another post. The one by Hochmuth gets to much the same point: In Twitter, you have connections to a known group of people, and you can get a message to them whenever you want to. No filtering, and no anonymity (at least in the public stream). Hochmuth’s post is a good analysis comparing Twitter with Facebook and Friendfeed as to how they connect with Audience. That’s an important idea for a marketer to think about.
