1. We found a lack of contrast between the categories menu and the main content part. There is no clear separation between them. So now you can see a relatively high contrast between the categories menu and the main content part. You would not be easily distracted by the menu when you are reading the posts.

2. The old design was too generic, we would like to have a unique theme for WebAppers. So that people can recognize WebAppers by looking at the site design.

3. There is too much white in the old design. It makes your eyes feeling uncomfortable when looking at the bright white screen for a period of time. And also We found the old design a not too much design elements, so that we have more design elements and patterns within this new design.

4. We always found the commenting section of the old theme a bit boring. At the same time, Automattic (Owned Wordpress) has just acquired Gravatar recently, it is now more than 3 times as fast and all paid features are now free for all. So that, we have implemented the Gravatar system on the commenting section of WebAppers, you can see your avatar next to your comments. I hope this can make the commenting section a little bit more interesting and encourage more people to discuss and comment on the posts.

5. Compared to the old clustered footer, the new footer is much simpler and useful.

6. We are trying to separate Components Resources and Design Related Resources on the Right Hand Side Categories Menu. Currently, the categories menu is a bit messy.

If it’s just for the hell of, don’t bother!
Tweak it if you want, but I don’t see the point in changing the whole thing.
