Though this blog is using blogger default core or CSS, it has been modified like mad till it don't resemble the original product. =3
Now releasing Code 3 extended (Untested), the new core meets the new people.
Looks like different theme but it uses different core and it's about 1-3 KB smaller in code size.
For older old and stable release, come to this post. http://benjamineong.blogspot.com/2007/12/known-issues-blog-code.html
