Apart from being a user-friendly CMS, what makes WordPress really great is the support for plugins and themes. With a huge library of plugins and themes, you can instantly add new features and new skins to your blog without any coding on your part.However, if you have been blogging long enough, you will know that sometime a badly coded plugin can break the site. Worst still, it can even cause the site to crash. This goes the same for a new theme. Without any tweaking and configuration, 9 out of 10 times the theme won't look great on your site. For such cases, it is wise to test them out before making them live.
