Not everyone wants/needs/cares about using a blogging system like MovableType or WordPress. But if you do, and you are unsure as to which system to use, you may want to check out The Matrix. The CMS Matrix, that is.
The CMS Matrix site lists over 550 different CMS solutions. Some of these are free and some cost hundreds, if not, thousands of dollars. Some are all-in-one solutions and some are extendable through add-ins. Some are designed for single users and some can handle thousands.
The Matrix allows you to pick up 10 systems to do a side-by-side comparison. Each system's particulars regarding system requirements, security, support, ease of use, management, interoperability, flexibility, performance, built-in applications, and commerce are displayed for your perusal.
Although you may need to take some of the data points with a grain of salt (who knows where the info came from and how current it is), you can at least narrow down your search to a few candidates that you can then take a serious look at. YMMV. Use at your risk. Insert disclaimer here.
