I have an interesting idea for you, what the best you can do is to turn your personal blog look like these social media sites so that you can always have a feeling like you are working on these social media sites.
Here are some cool WordPress themes that look like FaceBook, Twitter and Digg.

P2 is a theme for WordPress that transforms a mild-mannered blog into a super-blog with features like inline comments on the homepage, a posting form right on the homepage, inline editing of posts and comments, real-time updates so new posts and comments come in without reloading

Digg Look -alike Theme -Digg WordPress Theme
This theme is based on the massive social media site Digg, designed by VCARS. There are a range of awesome features, along with step-by-step instructions on how to install all the plugins. We’ve added bonus visual luxuries like Youtube integration, and a Flickr stream.
[Bonus] Here is Google Chrome look-alike Theme
A lightweight theme based on the highly coveted Google Chrome browser.
Interesting. Visually, These can indeed motivate people to work well as they would see the online environment they’re familiar with
The facebook theme is quite an interesting one, and I can see that people who are dabbling in social media, or who are just total fb nutters will really go for this theme. Are these theme free to download, Shanker? I might as well add them to the collection. Sooner or later I’ll have the need to do something like this.

I liked the digg theme because it is more reader friendly clean and attractive.
