I changed the site’s skin the other day.  I was just sick of the dark screen and was yearning for something that looked bright, clean, and readable.  In addition to this, I added a couple of features recently that I want to alert the readership to.  Firstly, when you are viewing an individual post, you will be able to see related posts in the sidebar. 

Secondly, when you are leaving a comment and you are addressing someone specifically, try using an @ and their name.  It’ll link to them.  See this comment for an example of this.

Beyond that, there is only one other thing I’d point you to.  If you are a windows user, it might be really helpful to try out Windows Live Writer for publishing blog posts.  It can handle multiple accounts (wordpress, blogger, xanga, wordpress.com, etcetera) and makes everything a breeze.
