Ugh, I hate these "X looks like Y" articles.

What it comes down to is they are both trying to display the same data (picture, username, message, etc), and honestly, there are only a few ways to logically present this information. Eventually the web will migrate to a standard for displaying this kind of information.

It's like saying The New York Times looks like The Boston Globe (which looks like The Washington Post (which looks like The Wall Street Journal)).
