When I was teenager, I started blogging using Sina. It is a simple blog-publishing service with some customizable options. That was more than enough for a newbie who only knew some HTML and CSS. As time passed by, there is rumour that Sina was going to close its blog service. Therefore, I migrated my blog to Blogger. Blogger provides more customizable options. Other than CSS, you can use widgets. However, I was frustrated by the limited widgets and themes are not enough for me after a period of time.
