About short clear internet addresses

 I have over a hundred blogs, and for some of them a shorter address, like www.ParatiisiVoittaa.fi and www.EasyHealing.info for example. This kind of internet addresses are called domains, and one can buy such for a year at a time or for some years. In addition one needs domain hosting, which is maybe roughly the price of an ordinary domain. Some domains are very wanted, maybe good for some work, so such are often for sale for a much higher price. But a domain offers world-wide visibility, so it can also be problematic, if you are not looking at things from a so world-wide point of view.
