Which should you use? Wordpress vs Blogger. And when I say Wordpress as in self hosted Wordpress not the free hosted one at Wordpress.com. So maybe this comparison may not be so good, because Blogger/Blogspot is free hosted. So maybe the comparison should be self hosted blog vs free hosted blog.
Anyway, I am using both self hosted Wordpress and Google Blogger/Blogspot. Both has their pros and cons. Sometimes we don't want to rely 100% on the free offering because we may not be able to control what happens to the free hosted blog. However Google is a big and cash rich company so there is some assurance that Blogger/Blogspot will not have a major change in its structure anytime soon.
Wordpress as a free open source software has been improving over the years and it is getting better and better. With better user interface and ease of publishing as well as the many free template offering, one could easily set up on a web hosting company and start blogging or creating a website almost immediately.
However doing a self hosted blog like Wordpress do require some good maintenance. You must always make sure you have hardened it against malicious hackers. Just recently I receive some warning from my Wordpress security that some hacker from Ukraine tried to do SQL injection. They even attempted to guess what kind of plugin that I have and exploit those weaknesses found in those plugin that has not been properly programmed. And before that some Koren hacker also attempted to hack into my Wordpress installation.
I don't know why my Wordpress installation is now the target of malicious hacker nowadays. I never experience any on my other website Wordpress installation. Anyway one could never be careful. So If you are not the kind that like to update your installation and putting up various security to protect your installation, it might be best that you avoid installing Wordpress onto a self hosted web hosting company.
And the alternative? Build a free website using blogger/blogspot. Why didn't I suggest the free alternative at Wordpress.com? Well for one, you can't really customize the theme and if you want to place some banner ads like Google Adsense, you can't at all unless you sign up for their premium service. The idea here now is to build a free website blog.
And of course you want to plug in your domain name to personalize the website, you could only do so with Blogger but not at Wordpress.com
So when it comes to free hosted, Blogger is better than Wordpress. But for self hosted, there isn't any Blogger system around for you to install. So the best option is to use Wordpress but you must put in some effort to maintain it and secure it.
