What Weblog Software Should I Use?
WordPress.com and Blogger are two of the more popularly used free weblog services, and both could work well for a class that requires you to keep a weblog. Of the two, WordPress tends to be used more by more serious and professional bloggers. It may be the better choice for ethos if you intend to blog long term. While Blogger may be easier to use to start with due to its Google account integration, simpler content creation and management interface, and template customization engine, you may eventually outgrow it’s more limited feature set.
While Wordpress.com provides free hosting of a version of WordPress that offers limited features, there is also the WordPress.org community dedicated to sharing and developing WordPress as open source software. You can download the full WordPress version and install it on your own server or on a commercial hosting account that you subscribe to, giving you much more control over the configuration and hundreds of additional modules that you can use to expand the feature set. Installing WordPress on your own instead of using Wordpress.com, however, also means that you will have to keep up with security updates as they are released by WordPress to stop your site from being hacked.
Other free hosted blog sites, like Destructoid, cater to specific types of bloggers (in this case, videogamers) and allow people to set up their own blogs there for free. This can be a good choice because there will be plenty of other like-minded bloggers there for you to talk to. In any case, you can always change your mind later, so feel free to experiment until you find something that fits.
