[WordPress.org] Site maintenance With full control comes the inevitable maintenance. Some people see this as a very small price to pay and it is worth the “hassle”. Others see site maintenance as a chore. Quite frankly, if you’re a business and this turns you off… I’m not sure why you have a business anyway? :) Depending on your needs, site maintenance can actually be very easy and cheap (if not free). WordPress is always working hard to improve so updates come pretty frequently. How easy is it to update the software? It’s so easy that it takes about 2-3 clicks of a button. While you may find little problems most of the time after updating, you have to beware that the mixture of certain themes and plugins can cause your site to break. Each case/website is unique, so consult with your trusted web designer if you have questions. [WordPress.com] 
No maintenance You don’t ever have to worry about keeping your site updated because Automattic will automatically do it for you. :) You don’t ever have to worry if your theme or plugins are compatible with the update and this is perfect if all you want to do is write blogs!
