Why WordPress
Most people use either Blogger or WordPress for their blog, and there appears to be an ongoing debate as to which is best. I prefer to design my own blogs using Drupal, but that's not related to this topic. Regarding the Blogger versus WordPress argument, for serious bloggers there is only one answer.
WordPress.
That is saying nothing against Blogger: run from Google's hosting site known as Blogspot, Blogger is an easy blogging system to use, and being easy, it has very little opportunity for customization; however Google users can use Google's toolbar to add posts or online content to their blog at the click of a button. However, WordPress wins hands down when we consider serious bloggers seeking more detailed customization.
