One of the most important decisions when starting a blog is choosing what blog platform to use. The two most common ones are Blogger and Wordpress right now. I'm always seeing the question "Which blogging platform is best"? and to be honest one is not better than the other. The question should be "Which blogging platform is best for me and my blog"? I say that because what a blogger needs varies and you should do some research before choosing because you're probably not going to want to go to the trouble of switching your blog over to another platform if you change your mind. I started my blog in May 2011 using wordpress and decided a few months later that blogger had more of the features I wanted. Thankfully I was able to transfer everything over without a problem but some people have difficulties.
Having used both WordPress and Blogger I wanted to make a post comparing the different features of both to at least give you an idea.
Is a free google service that is intended to make it easy for beginners and attracts people that don't want to spend money on a blog. Blog Spot is a web log hosting service run by the people at blogger
It is totally free
You can use the Template Designer to customize fonts, colors, layouts etc, without having knowledge of HTML or CSS
You can monetize your blog with google AdSense or another ad services very easily
Integrates with all google services, i.g google friend connect, feedburner, google reader, etc.
Add a variety of gadgets or make your own, while being able to arrange them in your sidebar(s)
You can use the HTML editor for advanced editing and customizing.
The comment system they use is horrible (but you can install Disqus or Instense Debate to fix that problem)
There aren't a lot of templates to choose from
You can only create a maximum of 10 static pages
There are actually two versions, wordpress.com and wordpress.org. They are both very different from each other and very different from blogger. I only used Wordpress.com but Im going to share what I know about Wordpress.org so you can compare the differences.
You can choose from over 100 different themes

Their comment system is a lot better than bloggers.

This version is best for the more experienced tech savvy people. You have complete control over your blog because your paying for the web hosting. A lot of people use it to create sites for their business but it's also good for the everyday blogger.

More control over blog authors capabilities than blogger

When new versions are released you have to update them manually

By figuring out which features in a blogging platform are most important to you, you can then choose the platform thats best for you. For example, I was looking for something that didn't involve a lot of HTML (bc I'm horrible at it), I didn't really want to spend too much money or any at all, so that narrowed my choices down to WordPress.com or Blogger. I ended up picking WordPress than switching over to blogger bc I didn't do enough research. If you are deciding between wordpress.com or blogger than my advice would be to go with blogger. That's only my advice though, I say this bc even though wordpress does have a large amount of themes, you're limited to those themes since only some allow certain customizations and others don't. Blogger lets you upload a bunch of different third party templates or customize your own using the template designer. So there's no restrictions with blogger.
Hopefully this post helped you to see some of the main differences between blogger and wordpress so you can choose. Blogging is so much fun, but you dont want to pick the wrong platform and be unhappy with it. So do what I wish I did and really look at both options first and pick the right one for you and your blog.
