What are the disadvantages of a hosted blogging platform?

Although there are quite a few advantages to a hosted blogging system, the downsides to such a system are quite clear.

• Generic URL
  Having your own URL can be very helpful in establishing credibility and branding your blog. Many people perceive the hosted blog URLs to be less serious or to be more for hobbiests. Still, quite a few prominent organizations and well-known bloggers still use hosted blog options.
• Web design restrictions
  Many hosted blogs end up looking very similar to one another. Many hosted solutions charge extra for making small design refinements or for having access to some code like: CSS or HTML, in a limited way. Also default web design templates get used over and over for bloggers. Also, the hosted solutions never give you full control over your blog.
• No ownership
  While you do own the content that you produce for your blog, you do not own the system or the URL through which your blog operates. You are at the mercy of the hosting company that provides the hosted solution.
• Lack money-making tools
  Because you don't have the same control over your blog and the technology powering it, you won't have the same monitization options. This can limit your ability to make your blog into a revenue earning blog. Some hosted solutions even forbid you to commercialize your blog. If you are considering creating a blog to run as a business, a hosted solution may not be the best choice for you.
