While the entire blogosphere is waiting impatiently to jump in and discuss the virtues of WordPress 2.3, I'll give you something else to discuss.
Yes, WordPress is a "must have" for a serious blogger, especially if their topic is "making money" or "blogging" but, in many circumstances, Blogger is a superior platform and here are 3 reasons why.
Totally Free - No hosting, no domain, no expense whatsoever. How much explanation does this one need?
Super Simple User Interface - No complicated set up or installation. No downloading themes or plug-ins needed. Simply enter your username, password and email address, choose one of thirty-something templates, answer some simple questions and start posting.
No SEO Needed - The fact is Google loves Blogger. A frequently updated Blogger blog will be indexed quickly and rank pretty well for almost anything that is posted with virtually no Search Engine Optimization.
While a Blogspot address causes credibillity issues for business or "make money" blogs, the fact is, if your blog is simply a place to express yourself online, Blogger is a perfectly legitimate, acceptable and often superior platform.
