There are many plugins available, so you can create a blog with your personality. Today I searched some plugins and installed them into my WordPress.

The demo is showed on the sidebar for “Recent Comments” and “Recent Trackbacks”, and you can set your own formatting. It’s very useful! Here I just extract some features of this plugins.
