This document lists 10 reasons why you should not use a free blog service. It notes that free blog domains like .blogspot.com and .wordpress.com can negatively impact website authority, force ads, offer limited customization, plug-in support, and control over ads. Free blogs also risk being closed down or made paid, look unprofessional, may not allow selling or transferring the blog, or signing up for ad networks due to the domain name. The document recommends taking blogging seriously by not using a free service.
